    PURPOSE: Depression is common following acute coronary syndrome, and thus, it is important to provide knowledge to improve prevention and detection of depression in this patient group. The objectives of this study were to examine: (1) whether indicators of stressors and coping resources were risk...... factors for developing depression early and later after an acute coronary syndrome and (2) whether prior depression modified these associations. METHODS: The study was a register-based cohort study, which includes 87,118 patients with a first time diagnosis of acute coronary syndrome during the period...... 2001-2009 in Denmark. Cox regression models were used to analyse hazard ratios (HRs) for depression. RESULTS: 1.5 and 9.5 % develop early (≤30 days) and later (31 days-2 years) depression after the acute coronary syndrome. Among all patients with depression, 69.2 % had first onset depression, while 30...

    Evidence-practice gaps exist in the continuum of care for patients with acute coronary syndromes (ACS), particularly at hospital discharge. We aimed to describe the methodology and baseline results of the Discharge Management of Acute Coronary Syndromes (DMACS) project, focusing on the prescription of guideline-recommended medications, referral to cardiac rehabilitation and communication between the hospital, patient and their primary healthcare professionals. DMACS employed Drug Use Evaluation methodology involving data collection, evaluation and feedback, and targeted educational interventions. Adult patients with ACS discharged during a 4-month period were eligible to participate. Data were collected (maximum 50 patients) at each site through an inpatient medical record review, a general practitioner (GP) postal/fax survey conducted 14 days post discharge and a patient telephone survey 3 months post discharge. Forty-nine hospitals participated in the audit recruiting 1545 patients. At discharge, 57% of patients were prescribed a combination of antiplatelet agent(s), beta-blocker, statin and angiotensin-converting enzyme inhibitor and/or angiotensin II-antagonist. At 3 months post discharge, 48% of patients reported using the same combination. Some 67% of patients recalled being referred to cardiac rehabilitation; of these, 33% had completed the programme. In total, 83% of patients had a documented ACS management plan at discharge. Of these, 90% included a medication list, 56% a chest pain action plan and 54% risk factor modification advice. Overall, 65% of GPs rated the quality of information received in the discharge summary as 'very good' to 'excellent'. The findings of our baseline audit showed that despite the robust evidence base and availability of national guidelines, the management of patients with ACS can be improved. These findings will inform a multifaceted intervention strategy to improve adherence to guidelines for the discharge management of

    Objective: To determine the frequency of metabolic syndrome in male patients presenting with acute coronary syndrome Study design: A Descriptive study Place and duration of study: Armed Forces Institute of Cardiology and National Institute of Heart Diseases, Rawalpindi, from October 2007 to September 2008 Patients and Methods: Male patients with acute coronary syndrome (ACS) were included. Patients having angioplasty (PCI), coronary artery bypass surgery in the past and other co-morbid diseases were excluded. All patients were assessed for the presence of five components of metabolic syndrome including hypertension, HDL-Cholesterol and triglycerides, glucose intolerance and abdominal obesity. Systolic, diastolic blood pressures, waist circumference (WC) and body mass index (BMI) were measured. ECG, cardiac enzymes, fasting glucose and lipid profile were also done. Results: A total of 135 male patients of ACS were studied with a mean age of 54.26 +- 11 years. Metabolic syndrome (MS) was present in 55 (40.7%) patients. MS with all five components was documented in 4 (7.27%) while MS with four and three components was seen in 23 (41.81%) and 28 (50.90%) patients respectively. Only 24 (43.63%) patients with MS had diabetes mellitus, remaining 31(56.36%) were non diabetic. Frequencies of diabetes, hypertension and family history of CAD were significantly higher (p<0.05) in patients with metabolic syndrome as compared to patients with normal metabolic status. Conclusion: Metabolic syndrome is fairly common and important risk factor in patients of IHD. Other risk factors like smoking, dyslipidemia, hypertension and diabetes were also frequently found. Public awareness to control the risk factors can reduce the prevalence of CAD in our country. (author)

    Williams syndrome is a contiguous gene deletion syndrome resulting from a heterozygous deletion on chromosome 7q11.23, and is characterized by distinctive facial features and supravalvular aortic stenosis (SVAS). This syndrome rarely presents unpredictable cardiac death, and yet, as illustrated in the present case, it is still not possible to predict it, even on close monitoring. We herein describe the case of a 6-year-old Japanese girl with Williams syndrome, who had sudden cardiac collapse due to cardiac infarction after pharyngitis. Cardiac failure followed a critical course that did not respond to catecholamine support or heart rest with extracardiac mechanical support. Although marked coronary stenosis was not present, the left coronary cusp abnormally adhered to the aortic wall, which may synergistically cause coronary ostium occlusion with SVAS. Altered hemodynamic state, even that caused by the common cold, may lead to critical myocardial events in Williams syndrome with SVAS. © 2015 Japan Pediatric Society.

    Full Text Available OBJECTIVE: To assess safety and efficacy of coronary angioplasty with stent implantation in unstable coronary syndromes. METHODS: Retrospective analysis of in-hospital and late evolution of 74 patients with unstable coronary syndromes (unstable angina or infarction without elevation of the ST segment undergoing coronary angioplasty with stent placement. These 74 patients were compared with 31 patients with stable coronary syndromes (stable angina or stable silent ischemia undergoing the same procedure. RESULTS: No death and no need for revascularization of the culprit artery occurred in the in-hospital phase. The incidences of acute non-Q-wave myocardial infarction were 1.4% and 3.2% (p=0.6 in the unstable and stable coronary syndrome groups, respectively. In the late follow-up (11.2±7.5 months, the incidences of these events combined were 5.7% in the unstable coronary syndrome group and 6.9% (p=0.8 in the stable coronary syndrome group. In the multivariate analysis, the only variable with a tendency to significance as an event predictor was diabetes mellitus (p=0.07; OR=5.2; 95% CI=0.9-29.9. CONCLUSION: The in-hospital and late evolutions of patients with unstable coronary syndrome undergoing angioplasty with intracoronary stent implantation are similar to those of the stable coronary syndrome group, suggesting that this procedure is safe and efficacious when performed in unstable coronary syndrome patients.

    Elevated heart rate (HR) is associated with mortality in a number of heart diseases. We examined the long-term prognostic significance of HR at discharge in a contemporary population of patients with stable angina (SAP), non-ST-segment elevation acute coronary syndromes (NSTE-ACS), and ST-segment elevation myocardial infarction (STEMI) revascularized with percutaneous coronary intervention (PCI). Patients from the BASKET-PROVE trial, an 11-center randomized all-comers trial comparing bare-metal and drug-eluting stenting in large coronary vessels, were included. Discharge HR was determined from a resting ECG. Long-term outcomes (7 days to 2 years) were evaluated for all-cause mortality and cardiovascular death and non-fatal myocardial infarction. A total of 2029 patients with sinus rhythm were included, 722 (35.6%) SAP, 647 (31.9%) NSTE-ACS, and 660 (32.5%) STEMI. Elevated discharge HR was associated significantly with all-cause mortality: when compared to a reference of 90 bpm. For cardiovascular death/myocardial infarction, a discharge HR >90 bpm was associated with a hazard ratio of 6.2 (2.5-15.5, pacute coronary syndromes an elevated discharge HR was independently associated with poor prognosis. Conversely, a HR <60 bpm at discharge was associated with a good long-term prognosis irrespective of indication for PCI. © 2013.

    Congenital heart disease, primarily involving the left-sided structures, is often seen in patients with Turner Syndrome. Moreover, a few case reports have indicated that coronary anomalies may be more prevalent in Turner Syndrome than in the normal population. We therefore set out to systematically investigate coronary arterial anatomy by computed tomographic coronary angiography (coronary CTA) in Turner Syndrome patients. Fifty consecutive women with Turner Syndrome (mean age 47 years [17-71]) underwent coronary CTA. Patients were compared with 25 gender-matched controls. Coronary anomaly was more frequent in patients with Turner Syndrome than in healthy controls [20% vs. 4% (p = 0.043)]. Nine out of ten abnormal cases had an anomalous left coronary artery anatomy (absent left main trunk, n = 7; circumflex artery originating from the right aortic sinus, n = 2). One case had a tubular origin of the right coronary artery above the aortic sinus. There was no correlation between the presence of coronary arterial anomalies and karyotype, bicuspid aortic valve, or other congenital heart defects. Coronary anomalies are highly prevalent in Turner Syndrome. The left coronary artery is predominantly affected, with an absent left main coronary artery being the most common anomaly. No hemodynamically relevant coronary anomalies were found. Copyright © 2016 Society of Cardiovascular Computed Tomography. All rights reserved.

    Kounis syndrome is an acute coronary syndrome in the context of a hypersensitivity reaction. The main pathophysiological mechanism appears to be coronary vasospasm. We report the case of a patient with a history of allergy to quinolones, who was given ciprofloxacin before an elective surgical procedure and during drug administration developed symptoms and electrocardiographic changes suggestive of ST-segment elevation acute coronary syndrome. The drug was suspended and coronary angiography excluded epicardial coronary disease. Two hours after withdrawal of the drug the symptoms and ST elevation had resolved completely.

    2014-01-01

    Full Text Available Kawasaki syndrome is an acute systemic vasculitis of unknown etiology, which mainly affects children within the first 5 years of fife. At the present time, Kawasaki syndrome is recognized to be a leading cause of acquired organic heart diseases in children, which may result in coronary heart disease, myocardial infarction, and sudden death in children and young people. Most complications are associated with the cardiovascular system, with coronary artery changes in particular. Transthoracic echocardiography, which, besides coronary artery assessment, makes it possible to evaluate right and left ventricular systolic and diastolic functions and to study the cardiac valves and changes in pericardial effusion, is a major technique in Kawasaki syndrome. The paper outlines an update on the epidemiology, etiology, pathogenetic mechanisms, and pathomorphology of Kawasaki syndrome and considers possible coronary and noncoronary changes, outcomes, and clinical manifestations.

    Full Text Available BACKGROUND: Along with the established effects of opium on metabolic parameters, stimulatory or inhibitory effects of opium on metabolic syndrome are also predictable. This study aimed to examine the association of opium use with metabolic syndrome and its components. METHODS: This study was conducted on 5332 out of 5900 original sample participants enrolled in a population-based cohort entitled the Kerman Coronary Artery Disease Risk Study in Iran from 2009 to 2011. The subjects were divided into three groups of “non-opium users” (NOUs = 4340 subjects, “former opium users” (FOUs = 176 subjects, and dependent and occasional people named “current opium users” (COUs = 811 subjects. Metabolic syndrome was defined according to two International Diabetes Federation (IDF and National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III definition criteria. RESULTS: The overall prevalence of IDF defined-metabolic syndrome among NOUs, FOUs, and COUs was 36.4%, 27.3%, and 39.0%, respectively; which was significantly higher in the COUs group (P = 0.012. However, no significant difference was revealed across the three groups in prevalence of NCEP defined-metabolic syndrome (NOUs = 37.2%, FOUs = 30.1%, and COUs = 39.6%, P = 0.058. The odds for IDF defined-metabolic syndrome was higher in both COUs [odd ratio (OR = 1.28, P = 0.028] and FOUs (OR = 1.57, P = 0.045 compared with NOUs as the reference adjusting gender, age, body mass index, and cigarette smoking. However, the appearance of NCEP defined-metabolic syndrome could not be predicted by opium use. CONCLUSION: Opium use can be associated with an increased risk for metabolic syndrome based on IDF criteria and thus preventing the appearance of metabolic syndrome by avoiding opium use can be a certain approach to preventing cardiovascular disease.

    Background The incremental prognostic value of assessing the metabolic syndrome has been disputed. Little is known regarding its prognostic value in patients after an acute coronary syndrome. Design and methods The presence of metabolic syndrome (2005 International Diabetes Federation) was assessed at baseline in SOLID-TIMI 52, a trial of patients within 30 days of acute coronary syndrome (median follow-up 2.5 years). The primary endpoint was major coronary events (coronary heart disease death, myocardial infarction or urgent coronary revascularization). Results At baseline, 61.6% ( n = 7537) of patients met the definition of metabolic syndrome, 34.7% (n = 4247) had diabetes and 29.3% had both ( n = 3584). The presence of metabolic syndrome was associated with increased risk of major coronary events (adjusted hazard ratio (adjHR) 1.29, p metabolic syndrome was numerically but not significantly associated with the risk of major coronary events (adjHR 1.13, p = 0.06). Conversely, diabetes was a strong independent predictor of major coronary events in the absence of metabolic syndrome (adjHR 1.57, p metabolic syndrome identified patients at highest risk of adverse outcomes but the incremental value of metabolic syndrome was not significant relative to diabetes alone (adjHR 1.07, p = 0.54). Conclusions After acute coronary syndrome, diabetes is a strong and independent predictor of adverse outcomes. Assessment of the metabolic syndrome provides only marginal incremental value once the presence or absence of diabetes is established.

    The application of disease management algorithms by physician extenders has been shown to improve therapeutic adherence in selected populations. It is unknown whether this strategy would improve adherence to secondary prevention goals after acute coronary syndromes (ACSs) in a largely indigent county hospital setting. Patients admitted for ACS were randomized at the time of discharge to usual follow-up care versus the same care with the addition of a physician extender visit. Physician extender visits were conducted according to a treatment algorithm based on contemporary practice guidelines. Groups were compared using the primary end point of achievement of low-density lipoprotein treatment goals at 3 months after discharge and achievement of additional evidence-based practice goals. One hundred forty consecutive patients were randomized. A similar proportion of patients returned for study follow-up in both groups at 3 months (54 [79%]/68 in the usual care group vs 57 [79%]/72 in the intervention group; P = 0.97). Among those completing the 3-month visit, a low-density lipoprotein cholesterol level less than 100 mg/dL was achieved in 37 (69%) of the usual care patients compared with 35 (57%) of those in the intervention group (P = 0.43). There was no statistical difference in implementation of therapeutic lifestyle changes (smoking cessation, cardiac rehabilitation, or exercise) between groups. Prescription rates of evidence-based therapeutics at 3 months were similar in both groups. The implementation of a post-ACS clinic run by a physician extender applying a disease management algorithm did not measurably improve adherence to evidence-based secondary prevention treatment goals. Despite initially high rates of evidence-based treatment at discharge, adherence with follow-up appointments and sustained implementation of evidence-based therapies remains a significant challenge in this high-risk cohort.

    Full Text Available Aim: Coronary artery disease (CAD is one of the most frequent causes of mortality and morbidity worldwide. Coronary angiography is the gold standard for the anatomical diagnosis of coronary artery stenosis. Myocardial Perfusion Scintigraphy (MPS is a non-invasive imaging modality used for the diagnosis of CAD. In this study, we aimed to compare the findings of MPS and coronary angiogram. Material and Method: Eighty-one patients (37 males, 44 females; mean age 55 ± 10.95 years with angina and detected perfusion defects on MPS were included in this study. All of the patients underwent coronary angiogram. A narrowing %u2265 50% was considered pathological on the coronary angiography. Results: Findings of the coronary angiogram and MPS were compared and found consistent in 51 (63% patients. A coronary narrowing < 50% was detected by coronary angiogram in 4 (5% of the remaining patients. Coronary angiogram was found to be normal in the remaining 26 patients (32% and these patients were evaluated as cardiac syndrome X (CSX known as microvascular angina (MA. Discussion: The findings showed that MPS is superior to coronary angiogram in the early diagnosis of myocardial perfusion disorders at the microvascular level. Therefore, we concluded that MPS should be the primary diagnostic tool to begin treatment before an anatomically large narrowing occurs in the coronaries.

    Depression is common and associated with poor prognosis in acute coronary syndrome (ACS). There are few reports on the predictors of incident and persistent post-discharge depressive disorders in ACS. This study aimed to investigate the incidence and persistence of depressive disorder over a one year follow-up, and predictors of these outcomes. 1152 patients with recently developed ACS were recruited at baseline, and 828 were followed one year thereafter. Depressive disorder (major and minor) was diagnosed according to DSM-IV criteria, and analyzed according to baseline prevalence, and follow up incidence and persistence. Of 446 baseline participants with depressive disorders, 300 were randomized to a 24-week double blind trial of escitalopram or placebo, while the remaining 146 received medical treatment as usual. Associations of baseline socio-demographic and clinical characteristics with depressive disorder were investigated using logistic regression models. Two-week prevalence, and one-year incidence and persistence of depressive disorder were 38.7%, 13.1%, and 46.3%, respectively. Baseline depressive disorder was independently associated with female, lower educational level, previous ACS and higher heart rate. Incident depressive disorder was independently predicted by current unemployment, family history of depression, higher baseline Hamilton Depression Rating Scale(HAMD) score and lower left ventricular ejection fraction, and persistent depressive disorder by higher baseline HAMD score and the placebo or medical treatment as usual group in the 24-week trial. The generalizability should be considered since this study conducted in a single center. Depressive disorder in ACS patients is common and often persistent, and is associated with baseline characteristics and insufficient treatment. Appropriate detection and treatment of depressive disorder are clearly important in ACS patients. Copyright © 2015 Elsevier B.V. All rights reserved.

    Background: Advances in computer tomography (CT) imaging technology in recent years have facilitated the possibility of noninvasive coronary angiography. Purpose: To compare the diagnostic accuracy of 64-channel multidetector computed tomography (MDCT) with conventional invasive coronary angiography (ICA) for the detection of significant coronary stenosis in patients with acute coronary syndrome (ACS). Material and Methods: MDCT was performed in 60 patients classified with non-ST-elevation infarction (NSTEMI) or unstable angina and scheduled for ICA within 3 days. The diagnostic accuracy of MDCT was evaluated using quantitative coronary angiography (QCA) as the gold standard. Results: 48 out of 60 patients had interpretable scans by both MDCT and ICA. On a segment-based analysis, 488 out of 665 segments with a diameter of =1.5 mm, as defined by QCA, were interpretable by MDCT. Sensitivity was 78%, specificity 87%, positive predictive value 47%, and negative predictive value 97% in detecting and excluding significant coronary stenosis, as defined with MDCT. On a per patient-based analysis, sensitivity was 89%, specificity 50%, positive predictive value 84%, and negative predictive value 60%. Conclusion: Limited diagnostic accuracy restricts the usefulness of coronary MDCT in patient groups with a high pretest probability of disease, such as in acute coronary syndrome.

    Churg-Strauss Syndrome (CSS) is a rare vasculitis with multiorgan involvement. Cardiac manifestations are common causing serious complications. We report a case of CSS masquerading as a non-ST elevation myocardial infarction with heart failure. CSS should be considered in the differential diagnosis of an acute coronary syndrome(ACS)with normal coronary arteries when history of asthma, peripheral eosinophilia and multisystemic involvement is present.

Congenital cardiovascular abnormalities are found in approximately one third of Turner syndrome patients. Developments in diagnosis and treatment have decreased the rate of mortality related to these abnormalities. In recent years, many papers have mentioned that coronary artery disease developing at early ages in patients with Turner syndrome causes sudden deaths. The patient, a 27-year-old female was admitted to the emergency room with chest pain at rest. She was diagnosed with Turner Syndrome in her teenage years due to amenorrhea. Patients with ECG changes and cardiac enzyme elevations were treated with acute coronary syndrome. The young woman with Turner Syndrome have several risk factors for early Coronary Artery Disease development. In such cases, dramatic results like sudden death or heart attack at an early age may occur in cases of insufficient follow-up and treatment.

OBJECTIVE: The Brazilian Registry of Acute Coronary Syndrome is a multicenter national study aiming at providing data on clinical aspects, management and hospital outcomes of acute coronary syndrome in our country. METHODS: A total of 23 hospitals from 14 cities, participated in this study. Eligible patients were those who came to the emergency wards with suspected acute coronary syndrome within the first 24 hours of symptom onset, associated with compatible electrocardiographic alterations and/or altered necrosis biomarkers. Follow-up lasted until hospital discharge or death, whichever occurred first. RESULTS: Between 2003 and 2008, 2,693 ACS patients were enrolled, of which 864 (32.1% were females. T he final diagnosis was unstable angina in 1,141 patients, (42.4%, with a mortality rate of 3.06%, non-ST elevation acute myocardial infarction (AMI in 529 (19.6%, with mortality of 6.8%, ST-elevation AMI 950 (35.3%, with mortality of 8.1% and non-confirmed diagnosis 73 (2.7%, with mortality of 1.36%. The overall mortality was 5.53%. The multiple logistic regression model identified the following as risk factors for death regarding demographic factors and interventions: female gender (OR=1.45, diabetes mellitus (OR=1.59, body mass index (OR=1.27 and percutaneous coronary intervention (OR=0.70. A second model for death due to major complications identified: cardiogenic shock/acute pulmonary edema (OR=4.57, reinfarction (OR=3.48, stroke (OR=21.56, major bleeding (OR=3.33, cardiopulmonary arrest (OR=40.27 and Killip functional class (OR=3.37. CONCLUSION: The Brazilian Registry of Acute Coronary Syndrome data do not differ from other data collected abroad. The understanding of their findings may help promote better planning and management of acute coronary syndrome care

    Atherosclerosis is a chronic inflammatory disease of the vessel wall and a major cause of death worldwide. One of atherosclerosis’ most dreadful complications are acute coronary syndromes that comprise ST-segment elevation myocardial infarction, non-ST-segment elevation myocardial infarction, and unstable angina. We now understand that inflammation substantially contributes to the initiation, progression, and destabilization of atherosclerosis. In this review, we will focus on the role of inflammatory leukocytes, which are the cellular protagonists of vascular inflammation, in triggering disease progression and, ultimately, the destabilization that causes acute coronary syndromes.

    Full Text Available Aims. The priority of Chinese herbal medicines (CHMs plus conventional treatment over conventional treatment alone for acute coronary syndrome (ACS after percutaneous coronary intervention (PCI was documented in the 5C trial (chictr.org number: ChiCTR-TRC-07000021. The study was designed to evaluate the 10-year effectiveness of CHMs plus conventional treatment versus conventional treatment alone with decision-analytic model for ACS after PCI. Methods and Results. We constructed a decision-analytic Markov model to compare additional CHMs for 6 months plus conventional treatment versus conventional treatment alone for ACS patients after PCI. Sources of data came from 5C trial and published reports. Outcomes were expressed in terms of quality-adjusted life years (QALYs. Sensitivity analyses were performed to test the robustness of the model. The model predicted that over the 10-year horizon the survival probability was 77.49% in patients with CHMs plus conventional treatment versus 77.29% in patients with conventional treatment alone. In combination with conventional treatment, 6-month CHMs might be associated with a gained 0.20% survival probability and 0.111 accumulated QALYs, respectively. Conclusions. The model suggested that treatment with CHMs, as an adjunctive therapy, in combination with conventional treatment for 6 months might improve the long-term clinical outcome in ACS patients after PCI.

    The use of bivalirudin versus unfractionated heparin monotherapy in patients without ST-segment-elevation myocardial infarction is not well defined. The study population consisted of patients enrolled in the Evaluation of Drug-Eluting Stents and Ischemic Events (EVENT) registry with either non-ST-segment-elevation acute coronary syndromes or stable ischemic heart disease, who underwent percutaneous coronary intervention with either unfractionated heparin or bivalirudin monotherapy. Propensity score matching was used to adjust for baseline characteristics. The primary bleeding (in-hospital composite bleeding-access site bleeding, thrombolysis in myocardial infarction major/minor bleeding, or transfusion) and primary (in-hospital death/myocardial infarction) and secondary ischemic outcomes (death/myocardial infarction/unplanned repeat revascularization at 12 months) were evaluated. Propensity score matching yielded 1036 patients with non-ST-segment-elevation acute coronary syndromes and 2062 patients with stable ischemic heart disease. For the non-ST-segment-elevation acute coronary syndrome cohort, bivalirudin use was associated with lower bleeding (difference, -3.3% [-0.8% to -5.8%]; P=0.01; number need to treat=30) without increase in either primary (difference, 1.2% [4.1% to -1.8%]; P=0.45) or secondary ischemic outcomes, including stent thrombosis (difference, 0.0% [1.3% to -1.3%]; P=1.00). Similarly, in the stable ischemic heart disease cohort, bivalirudin use was associated with lower bleeding (difference, -1.8% [-0.4% to -3.3%]; P=0.01; number need to treat=53) without increase in either primary (difference, 0.4% [2.3% to -1.5%]; P=0.70) or secondary ischemic outcomes, including stent thrombosis (difference, 0.0% [0.7% to -0.7%]; P=1.00) when compared with unfractionated heparin monotherapy. Among patients with non-ST-segment-elevation acute coronary syndromes or stable ischemic heart disease undergoing percutaneous coronary intervention, bivalirudin use

    Acute coronary syndromes are a frequent manifestation of a coronary artery disease, usually being associated with chest pain and presenting as a medical emergency. Since a considerable number of patients with chest pain, however, have a non cardiac etiology of trier pain, properly triaging these patients represents a diagnostic challenge for physicians in the emergency department. As the available diagnostic procedures have limited accuracy, many different diagnostic strategies have been evaluated. Among these, radionuclide myocardial perfusion imaging (MPI) at rest or in combination with stress procedures has been investigated in many trails. MPI has been proven to be useful, especially in a patient population with a low to intermediate probability of an ischemic event. Perfusion scintigraphy has a high sensitivity in the detection of myocardial infarction and reveals an excellent negative predictive value, allowing a safe discharge strategy of patients with a negative scan result. Moreover, it enables risk stratification and provides incremental and independent prognostic information regarding short to long term future cardiac adverse events. Several cost effectiveness studies have shown that perfusion imaging leads to lower overall direct costs, mainly by a reduction of unnecessary hospital admissions and diagnostic angiograms, without worsening of the clinical outcome of these patients. As a possible study endpoint, myocardial perfusion imaging in the acute setting enables the quantification of salvaged myocardium and therefore the evaluation of treatment efficacy. Besides perfusion agents, several infarcts avid radiopharmaceuticals have been developed, which in part show promising results. However, larger randomized trials evaluating these tracers in clinical settings are needed to warrant routine clinical application

    The spectrum of acute coronary syndrome (ACS) including unstable angina, non-ST-elevation myocardial infarction and ST-elevation myocardial infarction accounts for increasing numbers of deaths among persons age > or = 65 years in the US. This is important given demographic changes involving falling birth rates and increasing life expectancy. Elderly patients are likely to benefit the most from treatment of ACS, even though community practice still demonstrates less use of cardiac medications as an early-invasive approach among this population.

    The purpose of this study was to investigate the relationship between heart rate at admission and in-hospital mortality in patients with ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation acute coronary syndrome (NSTE-ACS). Consecutive ACS patients admitted in 2008-2010 across 58 hospitals in six participant countries of the European Hospital Benchmarking by Outcomes in ACS Processes (EURHOBOP) project (Finland, France, Germany, Greece, Portugal and Spain). Cardiogenic shock patients were excluded. Associations between heart rate at admission in categories of 10 beats per min (bpm) and in-hospital mortality were estimated by logistic regression in crude models and adjusting for age, sex, obesity, smoking, hypertension, diabetes, known heart failure, renal failure, previous stroke and ischaemic heart disease. In total 10,374 patients were included. In both STEMI and NSTE-ACS patients, a U-shaped relationship between admission heart rate and in-hospital mortality was found. The lowest risk was observed for heart rates between 70-79 bpm in STEMI and 60-69 bpm in NSTE-ACS; risk of mortality progressively increased with lower or higher heart rates. In multivariable models, the relationship persisted but was significant only for heart rates >80 bpm. A similar relationship was present in both patients with or without diabetes, above or below age 75 years, and irrespective of the presence of atrial fibrillation or use of beta-blockers. Heart rate at admission is significantly associated with in-hospital mortality in patients with both STEMI and NSTE-ACS. ACS patients with admission heart rate above 80 bpm are at highest risk of in-hospital mortality.

    Along with the established effects of opium on metabolic parameters, stimulatory or inhibitory effects of opium on metabolic syndrome are also predictable. This study aimed to examine the association of opium use with metabolic syndrome and its components. This study was conducted on 5332 out of 5900 original sample participants enrolled in a population-based cohort entitled the Kerman Coronary Artery Disease Risk Study in Iran from 2009 to 2011. The subjects were divided into three groups of "non-opium users" (NOUs = 4340 subjects), "former opium users" (FOUs = 176 subjects), and dependent and occasional people named "current opium users" (COUs = 811 subjects). Metabolic syndrome was defined according to two International Diabetes Federation (IDF) and National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) definition criteria. The overall prevalence of IDF defined-metabolic syndrome among NOUs, FOUs, and COUs was 36.4%, 27.3%, and 39.0%, respectively; which was significantly higher in the COUs group (P = 0.012). However, no significant difference was revealed across the three groups in prevalence of NCEP defined-metabolic syndrome (NOUs = 37.2%, FOUs = 30.1%, and COUs = 39.6%, P = 0.058). The odds for IDF defined-metabolic syndrome was higher in both COUs [odd ratio (OR) = 1.28, P = 0.028)] and FOUs (OR = 1.57, P = 0.045) compared with NOUs as the reference adjusting gender, age, body mass index, and cigarette smoking. However, the appearance of NCEP defined-metabolic syndrome could not be predicted by opium use. Opium use can be associated with an increased risk for metabolic syndrome based on IDF criteria and thus preventing the appearance of metabolic syndrome by avoiding opium use can be a certain approach to preventing cardiovascular disease.

    The aim of our study was to evaluate the immediate results and long-term intake of anti-GP IIb / IIIa inhibitors for patients with acute coronary syndrome treated with coronary angioplasty. The use of anti-GP IIb / IIIa is a valid therapeutic option in patients with acute coronary syndrome with signs of severity and for patients undergoing complex angioplasty. Adverse effects of anti-GP IIb / IIIa can be seen to encourage vigilance and careful monitoring during the administration of these molecules and perfect knowledge of their pharmacological properties for appropriate use.

    Systemic autoimmune diseases are themselves a relevant and independent risk factor for atherosclerosis and coronary ectasia. We describe a case of a 58-year-old Caucasian man who was admitted to our department for unstable angina. History of asthma, paranasal sinus abnormality, and peripheral eosinophilia given a high suspicion of Churg-Strauss syndrome (CSS). Diagnosis was performed with 5 of the 6 American College of Rheumatology criteria. The knowledge that CSS is often associated with significant coronary artery involvement and the persistence of chest pain led us to performing immediately a coronary angiography. Coronary angiography showed diffuse ectasic lesions, chronic occlusion of left anterior descending artery with homocoronary collateral circulation from left circumflex artery and subocclusive stenosis in the proximal tract of posterior descending artery. The early recognition of CSS, an aggressive invasive diagnostic approach, and an early appropriate therapy are important to prevent the progressive and permanent cardiac damage in these patients. In the setting of a multidisciplinary approach, careful cardiac assessment is an essential step in CSS, even in mildly symptomatic patients. Copyright © 2015 Cardiological Society of India.

    We report a case of acute coronary syndrome in a patient with suspect Marfan syndrome, 25 days after emergent modified Bentall-De Bono intervention for acute type I peripartum aortic dissection. She was admitted to our intensive care unit because of unstable angina, caused by critical blood flow reduction in a large portion of the myocardium, according to the severity of the symptoms and the electrocardiographic alterations. Coronary angiography showed a sub-occlusive stenosis of the left main coronary artery as a result of the dissection extension to the coronary ostium. Because of the high risk related to heart surgery, the patient was successfully treated by unprotected angioplasty and drug-eluting stent positioning. Short- and mid-term outcomes were favourable. Subsequent tests confirmed the diagnosis of Marfan syndrome. After 2 years of follow-up, the patient remains asymptomatic and in good health. To our knowledge, this is the first report of a successful percutaneous intervention of the left main coronary artery in a patient with Marfan syndrome who had already undergone ascending aortic root and valve replacement by the Bentall-De Bono procedure for acute dissection.

    To determine the accuracy of 64 MDCT coronary CTA (CCTA) compared to coronary angiography in low risk patients with stable angina and acute coronary syndrome and determine the number of significant coronary artery stenoses ( 50%) in these patients. Materials and methods. Fifty-five patients underwent CCTA using a 32 MDCT unit with z flying focus allowing the acquisition of 64 slices of 0.6 mm thickness as well as coronary angiography (gold standard). Nine patients were excluded due to prior coronary artery bypass surgery (n=4), insufficient breath hold (n=3), calcium scoring>1000 (n=1) and delay between both examinations over 4 months (n=1). Forty-six patients: 27 males and 19 females were included. CCTA results were compared to coronary angiography per segment and artery with threshold detection of stenoses 50%. The degree of correlation between both examinations was performed using a regression analysis with a Pearson correlation coefficient<0.05 considered significant. The overall accuracy of CCTA was 90%; limitations related to the presence of calcifications, motion artifacts or insufficient vessel opacification. The correlation for all analyzed segments was 96.4%. Thirty-eight of 50 significant stenoses seen on coronary angiography were correctly detected on CCTA. Sensitivity, specificity, PPVC and NPV for detection of stenoses 50% were 76%, 98.3%, 80.3% and 97.7% respectively. Evaluation per segment had a NPV of 96.8% (interventricular and diagonal segments) to 100% (main trunk). Our results for specificity and NPV are similar to reports from the literature. This suggests that CCTA in this clinical setting may replace coronary angiography.

    Full Text Available OBJECTIVE: This study evaluated the manner in which coronary dominance affects in-hospital outcomes of acute coronary syndrome (ACS patients undergoing percutaneous coronary intervention (PCI. BACKGROUND: Previous studies have shown that left dominant coronary anatomies are associated with worse prognoses in patients with coronary artery disease. METHODS: Data were analyzed from 4873 ACS patients undergoing PCI between September 2008 and April 2013 at 14 hospitals participating in the Japanese Cardiovascular Database Registry. The patients were grouped based on diagnostic coronary angiograms performed prior to PCI; those with right- or co-dominant anatomy (RD group and those with left-dominant anatomy (LD group. RESULTS: The average patient age was 67.6±11.8 years and both patient groups had similar ages, coronary risk factors, comorbidities, and prior histories. The numbers of patients presenting with symptoms of heart failure, cardiogenic shock, or cardiopulmonary arrest were significantly higher in the LD group than in the RD group (heart failure: 650 RD patients [14.7%] vs. 87 LD patients [18.8%], P = 0.025; cardiogenic shock: 322 RD patients [7.3%] vs. 48 LD patients [10.3%], P = 0.021; and cardiopulmonary arrest: 197 RD patients [4.5%] vs. 36 LD patients [7.8%], P = 0.003. In-hospital mortality was significantly higher among LD patients than among RD patients (182 RD patients [4.1%] vs. 36 LD patients [7.8%], P = 0.001. Multivariate logistic regression analysis revealed that LD anatomy was an independent predictor for in-hospital mortality (odds ratio, 1.75; 95% confidence interval, 1.06-2.89; P = 0.030. CONCLUSION: Among ACS patients who underwent PCI, LD patients had significantly worse in-hospital outcomes compared with RD patients, and LD anatomy was an independent predictor of in-hospital mortality.

    Full Text Available Background: Elevated mean platelet volume (MPV has been proposed as a risk factor for coronary artery disease (CAD and is associated with poor clinical outcome in acute coronary syndrome (ACS. However, some studies have contradictory findings. Hence, we aimed to evaluate the association of MPV with the presence of coronary collateral vessel (CCV in patients with ACS. Objective: To find MPV value in ACS patients and to find the predictive value of MPV in the spectrum of CAD and to examine whether levels of MPV predict the presence of CCVs. Methods: A total of 180 patients with first ACS were included in the study. MPV was measured. All patients underwent coronary angiography to know disease severity and CCVs. The CCVs are graded according to the Rentrop scoring system and according to coronary angiography results; patients were divided into two groups as Group 1 (poor CCV and Group 2 (good CCV. Results: The MPV was 10.74 ± 2 fl in poor collateral group patients and 11.01 ± 1.7 fl in good collateral group (P = 0.421. The presence of CCV was not significantly associated with high levels of MPV. MPV value did not show any prediction of the spectrum of CAD. Conclusion: MPV on admission was not associated with the development of CCV positively in patients with ACS. Furthermore, it is not associated with a number of vessel involvements.

    Full Text Available Backgroud: Acute coronary syndrome (ACS is an unstable and dynamic process that includes unstable angina, ST elevation myocardial infarction, and non-ST elevation myocardial infarction. Despite recent technological advances in early diognosis of ACS, differentiating between different types of coronary diseases in the early hours of admission is controversial. The present study was aimed to accurately differentiate between various coronary events, using machine learning techniques. Such methods, as a subset of artificial intelligence, include algorithms that allow computers to learn and play a major role in treatment decisions. Methods: 1902 patients diagnosed with ACS and admitted to hospital were selected according to Euro Heart Survey on ACS. Patients were classified based on decision tree J48. Bagging aggregation algorithms was implemented to increase the efficiency of algorithm. Results: The performance of classifiers was estimated and compared based on their accuracy computed from confusion matrix. The accuracy rates of decision tree and bagging algorithm were calculated to be 91.74% and 92.53%, respectively. Conclusion: The proposed methods used in this study proved to have the ability to identify various ACS. In addition, using matrix of confusion, an acceptable number of subjects with acute coronary syndrome were identified in each class.

    Objective:Environmental stresses, especially extreme cold and hot weathers, have tendency to have more admissions for acute coronary syndromes. Due to scarcity of local data, we studied the variation in patient admission rates with acute coronary syndrome according to different seasons. Study Design: Descriptive study. Place and Duration of Study: Coronary Care Unit, Civil Hospital and Pakistan Steel Hospital, Karachi, from January 2011 to December 2011. Methodology: The study group comprised consecutive patients with acute coronary syndrome (unstable angina, Non ST-Elevation Myocardial Infarction (NSTEMI), ST-Elevation Myocardial Infarction (STEMI) admitted to the coronary care unit. Patients with stable angina and valvular heart disease were excluded. Data was analyzed for admission according to different seasons, (winter, spring, summer and autumn). Results: The mean age of the 428 cases was 48.5 ± 10.4 years (range 27 to 73 years). Among the study group, 261 (61%) and 167 (39%) cases were male and female respectively. ST-elevation myocardial infarction, non ST-elevation myocardial infarction and unstable angina were present in 206 (48%), 128 (30%) and 94 (22%) respectively. Among the 428 patients, 184 (43%) cases had hypertension, 133 (31%) cases were smokers, 103 (24%) cases had dyslipidemia and diabetes mellitus and 08 (2%) cases had history of premature coronary artery disease. The number of patients admissions with acute coronary syndrome tended to change with sudden change in season. It increased in Winter 158 (36.9%) and Summer 130 (30.3%) in comparison to Spring 80 (18.69%) and Autumn 60 (14.02%) season. Conclusion: It was found variation in admission rates of acute coronary syndrome patients according to different seasons. The number of admissions not only increased in the cold season (winter) but also in hot season (summer) with sudden changes in temperature. (author)

    Diabetes mellitus is an independent risk factor for cardiovascular disease. To compare the efficacy of devices for continuous glucose monitoring and capillary glucose monitoring in hospitalized patients with acute coronary syndrome using the following parameters: time to achieve normoglycemia, period of time in normoglycemia, and episodes of hypoglycemia. We performed a pilot, non-randomized, unblinded clinical trial that included 16 patients with acute coronary artery syndrome, a capillary or venous blood glucose ≥ 140 mg/dl, and treatment with a continuous infusion of fast acting human insulin. These patients were randomized into 2 groups: a conventional group, in which capillary measurement and recording as well as insulin adjustment were made every 4h, and an intervention group, in which measurement and recording as well as insulin adjustment were made every hour with a subcutaneous continuous monitoring system. Student's t-test was applied for mean differences and the X(2) test for qualitative variables. We observed a statistically significant difference in the mean time for achieving normoglycemia, favoring the conventional group with a P = 0.02. Continuous monitoring systems are as useful as capillary monitoring for achieving normoglycemia. Copyright © 2012 Instituto Nacional de Cardiología Ignacio Chávez.

    Introduction: Myocardial bridge is an inborn anomaly of coronary artery development, when a part of it is submerged in a myocard, which is pressing the coronary artery to a systola and restrains coronary blood circulation. Generally this feature of coronary blood circulation does not cause any clinical symptoms because the 85% of coronary blood stream of the left ventricle is provided by diastolic filling. Hemodynamic changes in atherosclerosis, tahicardie, hypertrophie of myocard are leading to the manifestation of clinical symptoms of ischemia. The aim: The purpose of the investigation was to discover the features of clinical development of acute coronary syndrome caused by myocardial bridge of young patients without the features of atherosclerotical harm of coronary arteries. Materials and methods: Eight causes of acute coronary syndrome among patients of 28±8,5 years with myocardial bridge which was revealed during coronary angiography, were investigated. Standardized examination and conservative treatment of patients was held, except for three who have got interventional therapy. Results: According to our investigation, myocardial bridge of all investigated patients was located in the middle of the third front interventricular branch of the left coronary artery. Causes of acute coronary syndrome manifestation were tahicardia, spasms of coronary artery, inducted by iatrogenic factors hypertrophie of myocard, hypertrophic cardiomyopatie. Connection between the manifestation of clinical symptoms and length of tunneled segment which did not depend on the level of systolic compres was discovered. The results of conservative and interventional treatment were analyzed. Conclusions: Myocardial bridge can be the cause of myocardial ischemia among patients without signs of coronary atherosclerosis with additional hemodynamic risk facts such as tahicardia, spasms of coronary artery, hypertrophie of myocard. Clinical symptomatology of the acute coronary syndrome is more

    Full Text Available Background: Gender differences among patients with the acute coronary syndrome is still being debated, no research has been done on gender inequality among coronary syndrome patients in Sudan. Objectives: To study gender differences in presentation, management, and outcomes of acute coronary syndrome in Sudan. Subjects and Methods: This cross-sectional descriptive longitudinal study was conducted in Omdurman Teaching Hospital between July 2014 and August 2015. Patients were invited to sign a written informed consent form, were interviewed and examined by a physician, and then followed during their hospital stay. Information collected includes coronary risk factors, vital signs, echocardiography findings, arrhythmias, heart failure, cardiogenic shock, and death. The Ethical Committee of Omdurman Teaching Hospital approved the research. Results: A total of 197 consecutive acute coronary syndrome patients were included, 43.1% were females. A significant statistical difference was evident between males and females regarding the type of acute coronary syndrome, its presentation, and time of presentation to the hospital, smoking, and receipt of thrombolysis (P 0.05. Conclusion: Women were less likely to receive thrombolytic therapy, present with chest pain, and diagnosed with ST-segment elevation myocardial infarction. No gender differences were found in acute coronary syndrome risk factors apart from smoking, which was more common in males, and there were no differences between males and females as regards in-hospital complications.

    Currently, cardiac computed tomography (CT) is increasingly being implemented into clinical algorithms, primarily due to substantial technical advances over the last decade. Its use in the setting of suspected acute coronary syndrome is of particular relevance, given the high degree of accumulating scientific evidence of improving patient outcomes. Performing cardiac CT requires specific knowledge on the available scan acquisitions and patient preparation. Also, expertise is required in order to interpret the coronary and extra-coronary findings adequately. The present article provides an overview of the different aspects on the use of cardiac CT in the setting of acute coronary syndrome.

Current standard antithrombotic therapy after coronary stent implantation consists of lifelong aspirin and clopidogrel for a variable period depending in part on the stent type. Despite its well-established efficacy in reducing cardiac-related death, myocardial infarction, and stroke, dual antiplatelet therapy with aspirin and clopidogrel is not without shortcomings. While clopidogrel may be of little beneficial effect if administered immediately prior to PCI and may even increase major bleeding risk if coronary artery bypass grafting is anticipated, early discontinuation of the drug may result in insufficient antiplatelet coverage with thrombotic complications. Optimal and rapid inhibition of platelet activity to suppress ischemic and thrombotic events while minimizing bleeding complications is an important therapeutic goal in the management of patients undergoing percutaneous coronary intervention. In this article we present an overview of the literature on clinical trials evaluating the different aspects of antithrombotic therapy in patients

    Full Text Available Background & Objectives: Coronary artery disease is the main cause of mortality in developing and industrial countries. Recently the involvement of infectious agents as a risk factor for Acute Coronary syndrome is drafted. So this study was designed to investigate the probable association between Acute Coronary syndrome and Helicobacter pylori infection.   Methods: This case-control study was carried out on 300 hospitalized patients with the diagnosis of Acute Coronary syndrome (UA and MI and 300 hospitalized patients without the history of coronary heart disease. Anti Helicobacter pylori Antibody level was determined by as an indicator of infection history. Using chi-square and t- test the results were analyzed in SPSS software.   Results: Results showed that 79 patients (26.3% in control group and 122 patients (40.6% in case group were seropositive and the difference was significant. Relationship between cronory diseases risk factors and levels of IgG was not significant. Also the results showed that the rate of hypertension in seropositive patients in case group was significantly upper than control group.   Conclusion: Regarding the findings of this study we can conclude that Helicobacter pylori infection probably is a risk factor for Acute Coronary Syndrome. Thus, further studies are needed to elucidate the association between Helicobacter pylori infection and Acute Coronary Syndrome.

    Full Text Available Identification of individuals who are at risk of suffering from acute coronary syndromes (ACS may allow to introduce preventative measures. We aimed to identify ACS-related urinary peptides, that combined as a pattern can be used as prognostic biomarker. Proteomic data of 252 individuals enrolled in four prospective studies from Australia, Europe and North America were analyzed. 126 of these had suffered from ACS within a period of up to 5 years post urine sampling (cases. Proteomic analysis of 84 cases and 84 matched controls resulted in the discovery of 75 ACS-related urinary peptides. Combining these to a peptide pattern, we established a prognostic biomarker named Acute Coronary Syndrome Predictor 75 (ACSP75. ACSP75 demonstrated reasonable prognostic discrimination (c-statistic = 0.664, which was similar to Framingham risk scoring (c-statistics = 0.644 in a validation cohort of 42 cases and 42 controls. However, generating by a composite algorithm named Acute Coronary Syndrome Composite Predictor (ACSCP, combining the biomarker pattern ACSP75 with the previously established urinary proteomic biomarker CAD238 characterizing coronary artery disease as the underlying aetiology, and age as a risk factor, further improved discrimination (c-statistic = 0.751 resulting in an added prognostic value over Framingham risk scoring expressed by an integrated discrimination improvement of 0.273 ± 0.048 (P < 0.0001 and net reclassification improvement of 0.405 ± 0.113 (P = 0.0007. In conclusion, we demonstrate that urinary peptide biomarkers have the potential to predict future ACS events in asymptomatic patients. Further large scale studies are warranted to determine the role of urinary biomarkers in clinical practice.

    Full Text Available Aim To compare plasma IL-10 concentrations in patients with Acute Coronary Syndrome (ACS with those in Coronary Artery Disease (CAD.Methods ACS patients hospitalized in intensive coronary care unit (ICCU of Cipto Mangunkusumo Hospital/Faculty of Medicine University of Indonesia (CMH/FMUI, Persahabatan Hospital, MMC Hospital, and Medistra Hospital, Jakarta, between May 2005 and May 2006, were included in this study. The ambulatory CAD patients were taken as comparator. The serum IL-10 level was measured by immunoassay method, and compared by using Independent Student’s t-test. To investigate whether IL-10 serum level could predict ACS, the sensitivity and specificity of this parameter towards ACS in various IL-10 serum levels were calculated as well.Results In this observational study, as many as 146 subjects were analyzed, consisting of 84 ACS patients, and 62 coronary artery disease (CAD. The IL-10 level was higher in the group of ACS patients (7.37 pg/mL + 7.81, CI 95% 5.68-9.07 than that in CAD patients (1.59 pg/mL + 1.55, CI 95% 1.2-1.98. The optimal cut-off point for serum IL-10level is >1.95 pg/mL, with 79.76 % sensitivity and 77.42 % specificity.Conclusion The IL-10 level was higher in the ACS patients compared to that in CAD patients. Serum IL-10 measurement is a quite superior method to distinguish acute and stable condition, eventhough it is not as good as hsCRP for the same purpose.

    Ivabradine is a heart rate reducing agent that exhibits anti-ischemic effects through the inhibition of funny electrical current in the sinus node resulting in heart rate reduction, thus enabling longer diastolic perfusion time, and reduced myocardial oxygen consumption without detrimental changes in arterial blood pressure, coronary vasomotion, and ventricular contractility. The current guideline-based clinical use of Ivabradine is reserved for patients with stable angina pectoris who cannot tolerate or whose symptoms are inadequately controlled with beta blockers. In patients with chronic heart failure and reduced ejection fraction, Ivabradine has demonstrated beneficial effects in improving clinical outcomes when added to conventional therapy. However, the role of Ivabradine in acute coronary syndromes has not been established. Based on the results from some relevant preclinical studies and a limited amount of clinical data that were reported recently, the role of Ivabradine in acute ischemic events warrants further investigation. The aim of this review is to provide an overview of the available literature on the potential role of Ivabradine in the clinical context of acute coronary syndromes. Copyright © 2017 Elsevier B.V.

    Full Text Available Abstract Objective: The incidence of depression and anxiety is higher in patients with acute coronary syndrome. The aim of this study is to determine whether experiencing acute coronary syndrome prior to open heart surgery affects patients in terms of depression, hopelessness, anxiety, fear of death and quality of life. Methods: The study included 63 patients who underwent coronary bypass surgery between January 2015 and January 2016. The patients were divided into two groups: those diagnosed after acute coronary syndrome (Group 1 and those diagnosed without acute coronary syndrome (Group 2. Beck depression scale, Beck hopelessness scale, Templer death anxiety scale and death depression scale, State-Trait anxiety inventory and WHOQOL-Bref quality of life scale were applied. Results: There was no significant difference between the two groups in terms of the total score obtained from Beck depression scale, Beck hopelessness scale - future-related emotions, loss of motivation, future-related expectations subgroups, death anxiety scale, the death depression scale, State-Trait Anxiety Inventory - social and environmental subgroups. The mental quality of life sub-scores of group 2 were significantly higher. The patients in both groups were found to be depressed and hopeless about the future. Anxiety levels were found to be significantly higher in all of the patients in both groups. Conclusion: Acute coronary syndrome before coronary artery bypass surgery impairs more the quality of life in mental terms. But unexpectedly there are no differences in terms of depression, hopelessness, anxiety and fear of death.

    Nuclear myocardial perfusion imaging is very effective in the evaluation of patients with suspicious acute coronary syndrome (ACS), for adequate diagnosis and treatment. There have been many clinical evidences to support the efficacy and cost-effectiveness. In addition, many authoritative guidelines support the utility of myocardial perfusion imaging in ACS with an appropriate diagnostic protocol. However, with the development of other cardiac imaging modalities, the choice of modality for the diagnosis of suspicious ACS now depends on the availability of each modality in each institute. Newly developed imaging technologies, especially including molecular imaging, are expected to have great potential not only for diagnosis but also for primary, secondary, and tertiary prevention of ACS.

    2015-10-01

    Diagnosing acute coronary syndrome (ACS) in the emergency department is often a complex process. Inflammatory markers might be useful for the rapid assessment of a patient's overall risk and might also help predict future episodes. The clinical use of these biomarkers could potentially lower the number of emergency visits and help in the prevention of future adverse events. The aim of this review was to evaluate the clinical utility of markers of cardiovascular inflammation in emergency patients with ACS. Based on a critical analysis of a selection of the literature, we concluded that none of the biomarkers of cardiovascular inflammation would at present be useful for stratifying risk in emergency situations, aiding prognosis, or guiding therapy for patients with ACS.

    The National Cardiovascular Disease (NCVD) Database Registry represents one of the first prospective, multi-center registries to treat and prevent coronary artery disease (CAD) in Malaysia. Since ethnicity is an important consideration in the occurrence of acute coronary syndrome (ACS) globally, therefore, we aimed to identify the role of ethnicity in the occurrence of ACS among high-risk groups in the Malaysian population. The NCVD involves more than 15 Ministry of Health (MOH) hospitals nationwide, universities and the National Heart Institute and enrolls patients presenting with ACS [ST-elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction (NSTEMI) and unstable angina (UA)]. We analyzed ethnic differences across socio-demographic characteristics, hospital medications and invasive therapeutic procedures, treatment of STEMI and in-hospital clinical outcomes. We enrolled 13,591 patients. The distribution of the NCVD population was as follows: 49.0% Malays, 22.5% Chinese, 23.1% Indians and 5.3% Others (representing other indigenous groups and non-Malaysian nationals). The mean age (SD) of ACS patients at presentation was 59.1 (12.0) years. More than 70% were males. A higher proportion of patients within each ethnic group had more than two coronary risk factors. Malays had higher body mass index (BMI). Chinese had highest rate of hypertension and hyperlipidemia. Indians had higher rate of diabetes mellitus (DM) and family history of premature CAD. Overall, more patients had STEMI than NSTEMI or UA among all ethnic groups. The use of aspirin was more than 94% among all ethnic groups. Utilization rates for elective and emergency percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG) were low among all ethnic groups. In STEMI, fibrinolysis (streptokinase) appeared to be the dominant treatment options (>70%) for all ethnic groups. In-hospital mortality rates for STEMI across ethnicity ranges from 8.1% to 10.1% (p = 0

    To investigate factors that influence annual prognosis in patients with non-ST-segment elevation acute coronary syndrome ((NSTEACS) concurrent with type 2 diabetes mellitus (DM2). The registry of patients with NSTEACS (non-ST-segment elevation myocardial infarction (NSTEMI), unstable angina) included 415 patients, of them 335 had no carbohydrate metabolic disorders, 80 had DM2. The follow-up period, during which the prognosis was evaluated in the patients, was one year after hospital discharge following the index NSTEACS event. Lipidogram readings and the serum levels of endothelin-1 (ET-1), sP-selectin, sE-selectin, and sPECAM were determined on day 10 after admission to hospital. All the patients underwent coronary angiography (CA), Doppler ultrasound of peripheral arteries during their hospital stay. The patients with DM2 versus those without diabetes proved to be significantly older and to have a higher body mass index; among them there were more women, they were noted to have more frequently hypertension and less frequently smoked. The presence of DM2 was associated with significantly increased intima-media thickness and higher GRACE scores (p=0.013) as compared to those in the patients with normal carbohydrate metabolism. There were significant differences in high-density lipoprotein levels that were lower, as well as in triglyceride levels and atherogenic index, which were higher in patients with DM2 than in those without this condition. In addition, there were significant differences in ET-1, sP-selectin, sE-selectin, and sPECAM levels that were significantly higher in the DM2 group. Moreover, the levels of ET-1 and sPECAM were above normal in both the DM and non-DM2 groups. Assessment of poor outcomes at one year of the observation established that cardiovascular mortality rates were significantly higher and coronary angiography was performed much less frequently in the DM2 group.

    Our aim was to report on a survey initiated by the European Association of Percutaneous Cardiovascular Interventions (EAPCI) collecting the opinion of the cardiology community on the invasive management of acute coronary syndrome (ACS), before and after the MATRIX trial presentation at the American College of Cardiology (ACC) 2015 Scientific Sessions. A web-based survey was distributed to all individuals registered on the EuroIntervention mailing list (n=15,200). A total of 572 and 763 physicians responded to the pre- and post-ACC survey, respectively. The radial approach emerged as the preferable access site for ACS patients undergoing invasive management with roughly every other responder interpreting the evidence for mortality benefit as definitive and calling for a guidelines upgrade to class I. The most frequently preferred anticoagulant in ACS patients remains unfractionated heparin (UFH), due to higher costs and greater perceived thrombotic risks associated with bivalirudin. However, more than a quarter of participants declared the use of bivalirudin would increase after MATRIX. The MATRIX trial reinforced the evidence for a causal association between bleeding and mortality and triggered consensus on the superiority of the radial versus femoral approach. The belief that bivalirudin mitigates bleeding risk is common, but UFH still remains the preferred anticoagulant based on lower costs and thrombotic risks.

    Full Text Available Spontaneous coronary artery dissection (SCAD is a rare cause of acute myocardial infarction that is more common in younger patients (under age 50 and in women. Although the etiology is not known, some predisposing conditions to SCAD are well known and include Marfan syndrome, pregnancy and peripartum state, drug abuse, and some anatomical abnormalities of the coronary arteries such as aneurysms and severe kinking. We describe a case of SCAD in a young woman who presented with sudden onset of chest pain and was admitted for the treatment of acute coronary syndrome. The coronary angiography showed dissection of the left anterior descending artery. The patient underwent successful percutaneous transluminal coronary angioplasty and stent placement.

    Subvalvular aneurysms are the least common type of left ventricular (LV) aneurysms and can be fatal. Subaortic LV aneurysms are much rarer than submitral LV aneurysms and mostly reported in infancy. They can be congenital or acquired secondary to infections, cardiac surgery or trauma. Here, we report a unique presentation of a large, idiopathic subaortic aneurysm in an adult masquerading as an acute coronary syndrome. Diagnosis was made with the help of a CT aortography. Aneurysm was surgically resected with good results. This case highlights the clinical presentation and management of subaortic aneurysms, an important differential for congenital aortic malformations. 2016 BMJ Publishing Group Ltd.

    It has been shown that cytomegalovirus (CMV) is present in coronary atherosclerotic plaques, but the clinical relevance of this presence remains to be elucidated. In this study we sought to examine CMV infection in atherosclerosis patients defined by different methods and to identify the clinical significance of CMV replication in the atherosclerotic plaques. The study included 105 consecutive patients who were admitted to our department and underwent coronary artery bypass grafting (CABG) surgical interventions. Coronary atherosclerotic specimens as well as 53 specimens from the mamillary artery of these same patients were analyzed. Enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) methods were used for evaluations. The CMV PCR test result was positive for 28 (26.7%) of patients with coronary artery atherosclerosis. After adjusting for other risk factors, coronary artery disease patients with a history of acute coronary syndrome were more likely to be positive for CMV PCR test (P=0.027; odds ratio: 4.2; 95% CI: 1.18-15.0). They were also more likely to have a positive family history for cardiovascular diseases (CVD). This study confirms previous evidence about the replication of CMV virus in the atherosclerotic plaques of coronary arteries and brings clinical significance to this observation by showing a higher prevalence of acute coronary syndromes in those patients with CMV-infected plaques. Our study also suggests a familial vulnerability to CMV replication in the coronary artery walls.

    Full Text Available Abstract Background Despite the existence of controversial debates on the efficiency of coronary endarterectomy (CE, it is still used as an adjunct to coronary artery bypass grafting (CABG. This is particularly true in patients with endstage coronary artery disease. Given the improvements in cardiac surgery and postoperative care, as well as the rising number of elderly patient with numerous co-morbidities, re-evaluating the pros and cons of this technique is needed. Methods Patient demographic information, operative details and outcome data of 104 patients with diffuse calcified coronary artery disease were retrospectively analyzed with respect to functional capacity (NYHA, angina pectoris (CCS and mortality. Actuarial survival was reported using a Kaplan-Meyer analysis. Results Between August 2001 and March 2005, 104 patients underwent coronary artery bypass grafting (CABG with adjunctive coronary endarterectomy (CE in the Department of Thoracic-, Cardiac- and Vascular Surgery, University of Goettingen. Four patients were lost during follow-up. Data were gained from 88 male and 12 female patients; mean age was 65.5 ± 9 years. A total of 396 vessels were bypassed (4 ± 0.9 vessels per patient. In 98% left internal thoracic artery (LITA was used as arterial bypass graft and a total of 114 vessels were endarterectomized. CE was performed on right coronary artery (RCA (n = 55, on left anterior descending artery (LAD (n = 52 and circumflex artery (RCX (n = 7. Ninety-five patients suffered from 3-vessel-disease, 3 from 2-vessel- and 2 from 1-vessel-disease. Closed technique was used in 18%, open technique in 79% and in 3% a combination of both. The most frequent endarterectomized localization was right coronary artery (RCA = 55%. Despite the severity of endstage atherosclerosis, hospital mortality was only 5% (n = 5. During follow-up (24.5 ± 13.4 months, which is 96% complete (4 patients were lost caused by unknown address 8 patients died (cardiac

    A 42-year-old woman with a history of aspirin-induced asthma was admitted with severe chest pain. Emergency coronary angiography revealed coronary artery spasms. The administration of vasodilators did not suppress the anginal symptoms, and the differential white blood cell count continued to show eosinophilia. The patient's symptoms of aspirin-induced asthma, eosinophilia and other allergic states led to the diagnosis of Churg-Strauss syndrome (CSS). After starting betamethasone therapy, the eosinophilia and cardiac symptoms rapidly disappeared. Although coronary vasospasms related to CSS are rare, the present case suggests that a differential white blood cell count should be obtained in patients with refractory coronary vasospasms.

    Von Willebrand disease (vWD) results from quantitative or qualitative deficiency of von Willebrand factor (vWF). The occurrence of myocardial infarction is very rare in patients with vWD. A few case reports of acute coronary syndrome (ACS) in vWD patients are present in the literature, but no definite management recommendations are available for such patients. We report a case of successful percutaneous coronary intervention (PCI) with bare-metal stent (BMS) implantation in a 46-year-old woman with type 1 vWD and history of coronary artery disease (CAD). She received periprocedural dual-antiplatelet therapy for 2 weeks and then continued aspirin without any bleeding complications. The optimal management of patients with vWD and ACS is complex and presents a therapeutic challenge. We propose that dual-antiplatelet therapy can be used safely in most vWD patients presenting with ACS as most of them are type 1 vWD. PCI with BMS can be done safely. Long-term management of these patients requires a systemic approach including hematological consultation, ascertaining vWF levels, as well as patient education and close outpatient follow-up.

    Type II diabetes and the metabolic syndrome are strong predictors of severity of occlusive coronary disease and poorer outcomes of coronary revascularization therapies. Coronary collateral growth can provide an alternative or accessory pathway of revascularization. However, collateral growth is impaired in type II diabetes and the metabolic syndrome. Although many factors necessary for collateral growth are known and many interventions have shown promising results in animal studies, not a single attempt to induce coronary collateral growth in human clinical trials has led to satisfactory results. Accordingly, the first part of this review outlines the known deleterious effects of diabetes and the metabolic syndrome on factors necessary for collateral growth, including pro-angiogenic growth factors, endothelial function, the redox state of the coronary circulation, intracellular signaling, leukocytes and bone marrow-derived progenitors cells. The second section highlights the gaps in our current knowledge of how these factors interact with the radically altered environment of the coronary circulation in diabetes and the metabolic syndrome. The interplay between these pathologies and inadequately explored areas related to the temporal regulation of collateral remodeling and the roles of the extracellular matrix, vascular cell phenotype and pro-inflammatory cytokines are emphasized with implications to development of efficient therapies.

    Full Text Available Background: Abdominal obesity is an important cardiovascular risk factor. Therefore, identifying the best method for measuring waist circumference (WC is a priority. Objective: To evaluate the eight methods of measuring WC in patients with acute coronary syndrome (ACS as a predictor of cardiovascular complications during hospitalization. Methods: Prospective study of patients with ACS. The measurement of WC was performed by eight known methods: midpoint between the last rib and the iliac crest (1, point of minimum circumference (2; immediately above the iliac crest (3, umbilicus (4, one inch above the umbilicus (5, one centimeter above the umbilicus (6, smallest rib and (7 the point of greatest circumference around the waist (8. Complications included: angina, arrhythmia, heart failure, cardiogenic shock, hypotension, pericarditis and death. Logistic regression tests were used for predictive factors. Results: A total of 55 patients were evaluated. During the hospitalization period, which corresponded on average to seven days, 37 (67% patients had complications, with the exception of death, which was not observed in any of the cases. Of these complications, the only one that was associated with WC was angina, and with every cm of WC increase, the risk for angina increased from 7.5 to 9.9%, depending on the measurement site. It is noteworthy the fact that there was no difference between the different methods of measuring WC as a predictor of angina. Conclusion: The eight methods of measuring WC are also predictors of recurrent angina after acute coronary syndromes.

  2. Optical Coherence Tomography Imaging in Acute Coronary Syndromes

    Full Text Available Optical coherence tomography (OCT is a high-resolution imaging technique that offers microscopic visualization of coronary plaques. The clear and detailed images of OCT generate an intense interest in adopting this technique for both clinical and research purposes. Recent studies have shown that OCT is useful for the assessment of coronary atherosclerotic plaques, in particular the assessment of plaque rupture, erosion, and intracoronary thrombus in patients with acute coronary syndrome. In addition, OCT may enable identifying thin-cap fibroatheroma, the proliferation of vasa vasorum, and the distribution of macrophages surrounding vulnerable plaques. With its ability to view atherosclerotic lesions in vivo with such high resolution, OCT provides cardiologists with the tool they need to better understand the thrombosis-prone vulnerable plaques and acute coronary syndromes. This paper reviews the possibility of OCT for identification of vulnerable plaques in vivo.

    Full Text Available Abstract Objective Behcet's is an idiopathic multi-organ syndrome, which may have onset during childhood. Vascular involvement is uncommon, with rarely reported coronary aneurysm formation. We present a case report of a teenager girl who developed recalcitrant life-threatening Behcet's vasculitis, involving both small and large venous and arterial systems including a giant coronary aneurysm. Case report De-identified data were collected retrospectively in case report format. Although our sixteen year old female with Behcet's vasculitis had resolution of many arterial aneurysms, she had persistent venous thrombosis of large vessels, as well as persistent, giant arterial aneurysms requiring intra-arterial coiling of a lumbar artery and coronary bypass grafting despite intensive immunosuppression including glucocorticoids, cyclophosphamide, infliximab, methotrexate, azathioprine and intravenous immunoglobulin. Conclusions Vascular manifestations may be seen in Behcet's syndrome, including asymptomatic coronary aneurysm, which may be refractory to immunosuppression and ultimately require surgical intervention. Increased awareness is essential for prompt diagnosis and management.

    Background: The frequency of conventional risk factors for acute coronary syndrome differs in women compared to men, both in the general population and in patients with acute coronary syndrome. Objective: To find out the frequency of conventional risk factors in patients with acute coronary syndrome in males and females that exists in Pakistani patient population. Design: Cross-sectional survey. Material and Methods: A total of one hundred patients with acute coronary syndrome who presented in the Cardiology Department, Mayo Hospital Lahore were interviewed between May, 2008 and March 2009. Patients were enquired about the presence of hypertension and diabetes mellitus. Information was also obtained regarding smoking and history of ischemic heart disease in their first degree relatives. Lipid profile was recorded from the investigation chart of every patient. Results: 91% of subjects had at least one risk factor out of four conventional factors. When comparing men and women, more women were hypertensive and diabetic (p = 0.003 and 0.009 respectively). None of the females had ever smoked as compared to 34% of males (P = <0.001). Conclusion: Women with acute coronary syndrome, when compared to men, have more prevalence of diabetes and hyper-tension, and less prevalence of smoking. Further research is needed to better understand the gender differences in various aspects of ischemic heart disease that exist in our population. (author)

    We report a case of 30 year old alcoholic male admitted with vomiting, drowsiness, limb weakness and fasciculations after alleged history of consumption of 30 ml of chlorpyriphos insecticide. He had low serum cholinesterase levels. With standard treatment for organophosphorus poisoning (OPP), he improved gradually until day 5, when he developed neck and limb weakness and respiratory distress. This intermediate syndrome was treated with oximes, atropine and artificial ventilation. During treatment, his ECG showed fresh changes of ST elevation. High CPK & CPK-MB levels, septal hypokinesia on 2D echo suggested acute coronary syndrome. Coronary angiography was postponed due to his bedridden and obtunded status. The patient finally recovered fully by day 15 and was discharged. Acute coronary syndrome is a rare occurrence in OP poisoning. The present case thus emphasises the need for careful electrocardiographic and enzymatic monitoring of all patients of organophosphorus poisoning to prevent potential cardiac complication which can prove fatal.

Recruited were 65 CHD patients including 37 cases of PTS and 28 cases of QDS. Serum endogenous metabolites in the two syndrome types were determined by gas chromatograph-mass spectrometer-computer (GC/MS), and their differences between their metabolic profiles analyzed. More than 100 chromatographic peaks were totally scanned. Chromatograms obtained was matched with mass spectrum bank, and finally we got the category contribution value of 46 kinds of substances. Results of MCTree analysis showed patients of PTS and patients of QDS could be effectively distinguished. Compounds contributing to identify the two syndromes were sequenced as serine, valine, 2 hydroxy propionic acid. Comparison of metabolites showed contents of serine and 2 hydroxy propionic acid were higher in patients of PTS than in patients of QDS (Pmetabonomics of CHD TCM syndrome types could provide material bases for TCM syndrome differentiation of CHD, indicating that metabonomics technologies might become a new research method for TCM syndrome typing.

    disorder in hyperthyroidism but paroxysmal tachycardia and atrial fibrillation are not rare. This can be explained by increased heart rate, cardiac output, blood volume, coronary artery flow and peripheral oxygen consumption in thyreotoxicosis [9]. Patients with coronary arteriosclerosis can develop angina pectoris during thyreotoxic stage, which can be explained by imbalance between cardiac demand and supply. Myocardial damage is often in thyrotoxic patients with chronic hart failure, together with myocardial infarction in patients without coronary disease [2,6]. Congestive heart failure and atrial fibrillation are relatively resistant to digitalis treatment because of high metabolic turn over of medication and excessive myocardial irritability in hyperthyro-idism [6]. Cardiovascular and myopathic manifestations predominate in older hyperthyroid patients (over 60 years and some of them can have only few symptoms of hyperthyroidism [1-3]. Thyrotoxic state characterized by fatigue, apathy, extreme weakness, low-grade fever and sometimes congestive heart failure are designated as apathetic hyperthyroidism. Such patients have small goiters, mild tachycardia and often cool and dry skin with few eye signs [6]. Patients with subclinical hyperthyroidism are at increased risk for atrial fibrillation [9]. Unstable angina and non-Q myocardial infarction (non ST elevation are acute manifestation of coronary artery disease. The acute coronary syndrome of unstable angina, non-Q myocardial infarction and Q-wave myocardial infarction have atherosclerotic lesions of the coronary arteries as a common pathogenic substrate. Errosions or ruptures of unstable atherosclerotic plaque triggered pathophysiologic processes, resulted in thrombus formation at the site of arterial injury. This leads to abrupt reduction or cessation through the affected vessel. Clinical manifestations of unstable angina and non-Q myocardial infarction are similar and diagnosis of non-Q myocardial infarction is made on

    Full Text Available The incidence of bradyarrhythmias in patients with acute coronary syndrome (ACS is 0.3% to 18%. It is caused by sinus node dysfunction (SND, high-degree atrioventricular (AV block, or bundle branch blocks. SND presents as sinus bradycardia or sinus arrest. First-degree AV block occurs in 4% to 13% of patients with ACS and is caused by rhythm disturbances in the atrium, AV node, bundle of His, or the Tawara system. First- or second-degree AV block is seen very frequently within 24 h of the beginning of ACS; these arrhythmias are frequently transient and usually disappear after 72 h. Third-degree AV blocks are also frequently transient in patients with infero-posterior myocardial infarction (MI and permanent in anterior MI patients. Left anterior fascicular block occurs in 5% of ACS; left posterior fascicular block is observed less frequently (incidence < 0.5%. Complete bundle branch block is present in 10% to 15% of ACS patients; right bundle branch block is more common (2/3 than left bundle branch block (1/3. In patients with bradyarrhythmia, intravenous (IV atropine (1-3 mg is helpful in 70% to 80% of ACS patients and will lead to an increased heart rate. The need for pacemaker stimulation (PS is different in patients with inferior MI (IMI and anterior MI (AMI. Whereas bradyarrhythmias are frequently transient in patients with IMI and therefore do not need permanent PS, there is usually a need for permanent PS in patients with AMI. In these patients bradyarrhythmias are mainly caused by septal necrosis. In patients with ACS and ventricular arrhythmias (VTA amiodarone is the drug of choice; this drug is highly effective even in patients with defibrillation-resistant out-of-hospital cardiac arrest. There is general agreement that defibrillation and advanced life support is essential and is the treatment of choice for patients with ventricular flutter/fibrillation.

    The advent of potent antiplatelet and antithrombotic agents over the past decade has resulted in significant improvement in reducing ischemic events in acute coronary syndrome (ACS). However, the use of antiplatelet and antithrombotic combination therapy, often in the settings of percutaneous coronary intervention (PCI), has led to an increase in the risk of bleeding. In patients with non-ST elevation myocardial infarction treated with antithrombotic agents, bleeding has been reported to occur in 0.4%–10% of patients, whereas in patients undergoing PCI, periprocedural bleeding occurs in 2.2%–14% of cases. Until recently, bleeding was considered an intrinsic risk of antithrombotic therapy, and efforts to reduce bleeding have received little attention. There have been increasing data demonstrating that bleeding is associated with adverse outcomes, including myocardial infarction, stroke, and death. Therefore, it is imperative to optimize patient outcomes by adopting pharmacological and nonpharmacological strategies to minimize bleeding while maximizing treatment efficacy. In this paper, we present a review of the bleeding classifications used in large-scale clinical trials in patients with ACS and those undergoing PCI treated with antiplatelets and antithrombotic agents, adverse outcomes, particularly mortality associated with bleeding complications, and suggested predictive risk factors. Potential mechanisms of the association between bleeding and mortality and strategies to reduce bleeding complications are also discussed. PMID:21915172

    To describe the clinical and procedural coronary chronic total occlusion (CTO) treatment results in a Nordic PCI centre during the implementation of a CTO treatment program. In a retrospective registry study, we assessed; (1) indication for the procedure, (2) Canadian Cardiovascular Society angina pectoris score (CCS)/New York Heart Association (NYHA) heart failure score, (3) lesion complexity and (4) adverse events during hospital stay and three months following the index procedure. The study cohort included 503 patients (594 lesions). From 2010 to 2013 96% of procedures were performed with antegrade wire-escalation technique and 4% performed using retrograde techniques, from 2013-2016 the corresponding numbers were 83% and 17.0%. The procedural success rate was 69%, increasing from 64% before to 72% (p = .06) after routinely using the retrograde approach. No individual patient characteristic, lesion variable or score was strongly associated with procedural success or failure. There were 4% serious procedure related complications. In patients with PCI of a CTO lesion only, 87% were in CCS or NYHA functional class ≥2 before the index procedure vs. 22% at follow-up. Routine use of retrograde techniques tended to increase the procedural success rate. Clinical results after three months were acceptable, but the complication rate was higher than for non-CTO PCI. Individual patient and lesion characteristics had a low predictability for procedural success. Therefore, clinical symptoms, objective signs of myocardial ischemia and procedural risk should be focus points in coronary chronic total occlusion treatment strategies.

    Background: Pseudoexfoliation syndrome (PEX) is recognised by chronic deposition of abnormal pseudoexfoliation material on anterior segment structures of the eye, especially the anterior lens capsule. In recent years, several studies have shown the presence of vascular, cardiac and other organ pseudoexfoliative material in patients with ocular pseudoexfoliation. Aims: The purpose of this study is to determine whether an association exists between ocular pseudoexfoliation and coronary artery disease, aortic aneurysms and peripheric vascular disease. Patients and Methods: 490 patients who underwent coronary angiography (CAG) at Kosuyolu Cardiovascula Research and Training Hospital were included in the study. Patients were evaluated for conventional risk factors such as age, sex, family history, hypertension, diabetes, dislipidemia and smoking. Detailed eye examinations including evaluation of lens were done in all patients. The presence of PEX material in the anterior segment was best appreciated by slit lamp after pupillary dilation. The patients were divided into two groups according to the presence of PEX, and compared for the presence of CAD and other risk factors. Results: CAD was present in 387 patients. 103 patients had normal coronary angiography. 20 (5.2 %) of CAD patients and 4 (3.9%) of normal CAG patients were found to have PEX (p>0.05). There was no significant relationship between CAD and the presence of PEX (p>0.05). When patients were grouped according to the presence of PEX, only age was significantly different between the two groups (r: 0.25, p<0.001). Conclusion: There is no significant relationship between the presence of PEX and CAD. Further studies in larger scales with elderly population may be more valuable. PMID:22558552

    Full Text Available Background: Burnout Syndrome is the extreme emotional response to chronic occupational stress, manifesting as physical and mental exhaustion. Although associated with higher prevalence of cardiovascular risk factors, no study so far has evaluated whether the Burnout Syndrome could be a prevalent factor in non-elderly individuals active in the labor market, admitted for acute coronary syndrome (ACS. Objective: To evaluate the prevalence of the Burnout Syndrome in non-elderly, economically active patients, hospitalized with ACS. Methods: Cross-sectional study conducted in a tertiary and private cardiology center, with economically active patients aged <65 years, hospitalized with diagnosis of ACS. The Burnout Syndrome was evaluated with the Burnout Syndrome Inventory (BSI, which assesses workplace conditions and four dimensions that characterize the syndrome: emotional exhaustion (EE, emotional distancing (EmD, dehumanization (De and professional fulfillment (PF. The Lipp’s Stress Symptoms Inventory for Adults (LSSI was applied to evaluate global stress. Results: Of 830 patients evaluated with suspected ACS, 170 met the study criteria, 90% of which were men, overall average age was 52 years, and 40.5% had an average income above 11 minimum wages. The prevalence of the Burnout Syndrome was 4.1%. When we evaluated each dimension individually, we found high EE in 34.7%, high De in 52.4%, high EDi in 30.6%, and low PF in 5.9%. The overall prevalence of stress was 87.5%. Conclusion: We found a low prevalence of Burnout Syndrome in an economically active, non-elderly population among patients admitted for ACS in a tertiary and private hospital.

    This study sought to compare the clinical outcomes of everolimus-eluting stents (EES) versus paclitaxel-eluting stents (PES) in patients with acute coronary syndromes (ACS) and stable coronary artery disease (CAD). Although randomized trials have shown superiority of EES to PES, the safety and efficacy of EES in ACS is unknown. We performed a patient-level pooled analysis from the prospective, randomized SPIRIT (Clinical Evaluation of the XIENCE V Everolimus Eluting Coronary Stent System) II, III, IV, and COMPARE (A Trial of Everolimus-Eluting Stents and Paclitaxel-Eluting Stents for Coronary Revascularization in Daily Practice) trials in which 2,381 patients with ACS and 4,404 patients with stable CAD were randomized to EES or to PES. Kaplan-Meier estimates of death, myocardial infarction (MI), ischemia-driven target lesion revascularization, and stent thrombosis were assessed at 2 years and stratified by clinical presentation (ACS vs. stable CAD). At 2 years, patients with ACS compared with stable CAD had higher rates of death (3.2% vs. 2.4%, hazard ratio [HR]: 1.37 [95% confidence interval (CI): 1.02 to 1.85], p = 0.04) and MI (4.9% vs. 3.4%, HR: 1.45 [95% CI: 1.14 to 1.85], p = 0.02). In patients with ACS, EES versus PES reduced the rate of death or MI (6.6% vs. 9.3%, HR: 0.70 [95% CI: 0.52 to 0.94], p = 0.02), stent thrombosis (0.7% vs. 2.9%, HR: 0.25 [95% CI: 0.12 to 0.52], p = 0.0002), and ischemia-driven target lesion revascularization (4.7% vs. 6.2%, HR: 0.69 [95% CI: 0.48 to 0.99], p = 0.04). In patients with stable CAD, EES reduced the rate of death or MI (4.5% vs. 7.1%, HR: 0.62 [95% CI: 0.48 to 0.80], p = 0.0002), stent thrombosis (0.7% vs. 1.8%, HR: 0.34 [95% CI: 0.19 to 0.62], p = 0.0002), and ischemia-driven target lesion revascularization (3.9% vs. 6.9%, HR: 0.55 [95% CI: 0.42 to 0.73], p SPIRIT II]; NCT00180310; SPIRIT III: A Clinical Evaluation of the Investigational Device XIENCE V Everolimus Eluting Coronary Stent System [EECSS] in the

    Periodontitis, a common polymicrobial inflammatory disease in the tooth supporting tissues, is a risk factor for coronary artery disease. One of the proposed underlying mechanisms is the systemic immune response to periodontal infection. We studied how serum antibodies against seven periodontal pathogens and their subgingival levels associate with each other, periodontitis, and coronary artery disease. The Parogene cohort included 505 Finnish patients (mean age 63 y) who underwent coronary angiography, and clinical and radiographic oral examinations. Coronary diagnosis was defined as no significant coronary artery disease (disease (≥50% stenosis, n = 184) and acute coronary syndrome (n = 169). Levels of subgingival Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Porphyromonas endodontalis, Prevotella intermedia, Tannerella forsythia, Campylobacter rectus, and Fusobacterium nucleatum were determined by checkerboard DNA-DNA hybridization. Serum antibody (IgA/IgG) levels were analyzed with enzyme-linked immunosorbent assay (ELISA). Aggregate IgA/IgG burdens were calculated by summing and standardizing the serum antibody levels. Patients with active periodontitis were characterized by higher levels of subgingival bacteria and corresponding IgA/IgG response. Quartiles 2-4 of serum IgA/IgG burden indicated higher risk for acute coronary syndrome (OR 1.84, 95%CI 1.01-3.35 for IgA; OR 1.87, 95%CI 1.01-3.46 for IgG) independently of established cardiovascular risk factors, body mass index, number of teeth, subgingival bacterial levels and periodontal diagnosis. Our findings support the hypothesis that the association between periodontitis and cardiovascular diseases is partly mediated by the immunologic response for periodontal pathogens.

    Despite a large volume of evidence supporting the use of dual antiplatelet therapy in patients with acute coronary syndrome, there remains major uncertainty regarding the optimal duration of therapy. Clinical trials have varied markedly in the duration of therapy, both across and within trials. Recent systematic reviews and meta-analyses suggest that shorter durations of dual antiplatelet therapy are superior because the avoidance of atherothrombotic events is counterbalanced by the greater risks of excess major bleeding with apparent increases in all-cause mortality with longer durations. These findings did not show significant heterogeneity according to whether patients had stable or unstable coronary heart disease. Moreover, the potential hazards and benefits may differ when applied to the general broad population of patients encountered in everyday clinical practice who have markedly higher bleeding and atherothrombotic event rates. Clinicians lack definitive information regarding the duration of therapy in patients with acute coronary syndrome and risk scores do not appear to be sufficiently robust to address these concerns. We believe that there is a pressing need to undertake a broad inclusive safety trial of shorter durations of therapy in real world populations of patients with acute coronary syndrome. The clinical evidence would further inform future research into strategies for personalised medicine. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Full Text Available A number of "interesting" risk markers have been proposed as providing prognostic information in acute coronary syndromes (ACS. Elevation in plasma inflammatory and necrosis biomarkers have been related to future cardiovascular events in individuals with or without prior myocardial infarction. Recently BNP and pro-BNP are entered in clinical practice to recognize patients at major risk, providing incremental information respect to the traditional markers. Together with these laboratory indexes, a few of promising laboratory markers once easily available, could become useful in identification of patients at high risk. Several studies evaluated many markers of platelet aggregation, endothelial dysfunction and vascular thrombosis, but it is not yet clear whether each of the proposed markers may provide incremental predictive information. We describe, following the most studies reported in literature, the laboratory markers with potential clinical and prognostic power that could early help physicians in the identifi cation of patients with impaired coronary disease and more narrowed coronary arteries.

    Full Text Available BACKGROUND It is observed that anaemia is a common problem in patients hospitalised for acute coronary syndromes. There have been reports in worldwide studies of an association between anaemia and poor prognosis in patients with Acute Coronary Syndromes (ACS. MATERIALS AND METHODS All consecutive patients having ST-elevation myocardial infarction, non-ST elevation myocardial infarction and unstable angina who were admitted in medicine ward, Medicine Intensive Care Unit (MICU, Cardiology Department (CRD, Cardiovascular and Thoracic Surgery (CVTS Department and incidentally found in other departments of Acharya Vinoba Bhave Rural Hospital admitted from 1st November 2014 to 31st December 2015 at AVBRH. Total 200 patients were included in the study. RESULTS Our study showed an association between haemoglobin levels and mean age (p=0.0001, gender (p=0.0001, risk factors like smoking (p=0.035, tobacco (p=0.001 and Killip’s class I (p=0.0001, III (p=0.0001 and IV (p=0.0001. On distribution of the MACE’s during hospital stay stratified with Hb levels, the results of analysis by Chi-square test showed that there were statistically significant differences at various haemoglobin levels in MACE’s as post-infarction angina, heart failure, VT/VF and death (p<0.05 for all. On distribution of the MACE’s during follow up on 30th day and on 180th day stratified with Hb levels, the results of analysis by Chi-square test showed that there were statistically significant differences at various haemoglobin levels in MACE’s as post-infarction angina, re-infarction, heart failure, VT/VF and death (p<0.05 for all. CONCLUSION To conclude our study results, it was found during the study that anaemia as an important risk factor was strongly associated with major adverse outcomes in patients with ACS. Our study suggested that there was a statistically significant correlation between the low Hb levels and MACE’s (post-infarction angina, re-infarction, heart

    Cannabis is one of the most widely used illicit substances worldwide, and it has the highest prevalence among drugs used in Egypt. The aims were to evaluate whether the use of cannabis is a risk factor of acute coronary heart disease in low-risk, young males and to compare the cardiac pathological changes between cannabis exposed and non-exposed ischemic patients. This was a cross-sectional study that was performed on 138 male patients, aged ≤ 40 years, with acute myocardial infarction who were admitted to the Cardiac Care Unit at the University Hospital. Urine samples were submitted for toxicological analysis using a homogenous enzyme immunoassay technique to determine the substance of use. The patients were divided into three groups: group 1 (n = 23), cannabis-positive only patients; group 2 (n = 28), patients positive for any other substance of use; and group 3 (n = 34), patients negative for any substance of use. Smoking was prominent, whereas group 1 had no other risk factors. In groups 1 and 2, ST-segment elevation myocardial infarction (STEMI) was dominant, whereas no ST-segment elevation myocardial infarction (NSTEMI) was prominent in group 3. Ischemic resting wall motion abnormalities were presented in 47.8% of group 1 and in only 11.8% of group 3. None of group 1 had normal coronaries, whereas 14.3% of group 3 had normal coronaries. Significant changes in echocardiography and angiography were observed between group 1 and other groups. Cannabis smoking could be a potential risk factor for the development of cardiac ischemia.

    Data on the effect of fasting on coronary disease are rare and controversial. The aim of our study was to investigate the influence of Ramadan on the prevalence of acute coronary syndrome among chest pain patients in the emergency department of Monastir. It was a prospective study, performed in the emergency department of Fattouma Bourguiba University Hospital of Monastir, during the 3 months before, during and after Ramadan from 2012 to 2014. We included all patients with non-traumatic chest pain during the study period. Data were collected using a standardized form. The uniformity chi 2 test, ANOVA test, Kruskal-Wallis test were performed at the 5% level. Binary logistic regression model was used for multivariate analysis. The SCA prevalence was 17% a month before Ramadan, 22% during Ramadan and 28% one month after Ramadan (p = 0.007). According to the results of the multivariate analysis, the period of Ramadan is not associated with increase of risk of SCA whereas the risk doubles after Ramadan in all group (p = 0.001). In subgroups analysis, the period of R was associated with an amplification of risk in men aged more than 55 years and women older than 65 years (OR: 2.1; p = 0.020) and among subjects with hypertension (OR: 2.4, p = 0.007). Ramadan and Shawwal were not associated with an increase of risk among subjects without CVX risk factor. We have demonstrated that the risk of SCA has increased in Ramadan only among the elderly and patient with hypertension. The increased risk in Shawwal can be explained by the lifting of dietary restriction.

  19. Antipsychotic Medications and Risk of Acute Coronary Syndrome in Schizophrenia: A Nested Case-Control Study.

    Directory of Open Access Journals (Sweden)

    Hsing-Cheng Liu

    Full Text Available This study assessed the risk of developing acute coronary syndrome requiring hospitalization in association with the use of certain antipsychotic medications in schizophrenia patients.A nationwide cohort of 31,177 inpatients with schizophrenia between the ages of 18 and 65 years whose records were enrolled in the National Health Insurance Research Database in Taiwan from 2000 to 2008 and were studied after encrypting the identifications. Cases (n = 147 were patients with subsequent acute coronary syndrome requiring hospitalization after their first psychiatric admission. Based on a nested case-control design, each case was matched with 20 controls for age, sex and the year of first psychiatric admission using risk-set sampling. The effects of antipsychotic agents on the development of acute coronary syndrome were assessed using multiple conditional logistic regression and sensitivity analyses to confirm any association.We found that current use of aripiprazole (adjusted risk ratio [RR] = 3.68, 95% CI: 1.27-10.64, p<0.05 and chlorpromazine (adjusted RR = 2.96, 95% CI: 1.40-6.24, p<0.001 were associated with a dose-dependent increase in the risk of developing acute coronary syndrome. Although haloperidol was associated with an increased risk (adjusted RR = 2.03, 95% CI: 1.20-3.44, p<0.01, there was no clear dose-dependent relationship. These three antipsychotic agents were also associated with an increased risk in the first 30 days of use, and the risk decreased as the duration of therapy increased. Sensitivity analyses using propensity score-adjusted modeling showed that the results were similar to those of multiple regression analysis.Patients with schizophrenia who received aripiprazole, chlorpromazine, or haloperidol could have a potentially elevated risk of developing acute coronary syndrome, particularly at the start of therapy.

On the other hand, lipid profile modification after a cardiovascular event related to acute coronary syndrome (ACS has been recognized. The prevalence of conventional risk factors and the lipid profile at the time of admission in patients with ACS and significant CAD (stenosis ≥50% determined through coronary angiography is not well described. Methods: We studied 3,447 patients with a diagnosis of ACS and significant CAD with stenosis ≥50%, as shown on angiography. We recorded the presence of conventional risk factors, including smoking, hypertension, dyslipidemia, and diabetes. In addition, we analyzed the lipid profiles within the first 24 hours of admission. We analyzed the studied population and compared findings according to sex.Results: Most patients (81.7% were male. ST-elevation myocardial infarction was present in 51.3% of patients, and non-ST-elevation acute coronary syndrome was present in 48.7%. The most frequent risk factor was smoking, which was present in 68% of patients, followed by hypertension (57.8%, dyslipidemia (47.5%, and diabetes (37.7%. In women, the most frequent risk factors were hypertension, diabetes, and dyslipidemia, whereas in men, smoking was the most frequent. We identified at least one risk factor in 95.7% of all patients, two or three risk factors in 62%, and four risk factors in 8.6% of patients. The lipid profile analysis revealed that

    Full Text Available Introduction: It has been argued in current studies that anabolic androgenic steroids (AAS are misused by a great number of bodybuilders and athletes. However, there is diverse and often conflicting scientific data on the cardiac and metabolic complications caused by the misuse of AAS. There may be various reasons for myocardial infarction (MI with normal coronary arteries. However, for the majority of patients, the exact cause is still unknown. Case report: A 32 year-old male who was complaining about severe chest pain was admitted to our emergency department. He had been taking methenolone acetate 200 mg weekly for a period of three years for body building. His cardiac markers were significantly elevated and electrocardiogram (ECG showed peaked T waves in all derivations, which did not show ST elevation or depression. Both right and left coronary artery systems were found to be completely normal as a result of the angiogram. Conclusion: The purpose of this study is to show that AAS induced MI can be encountered with normal coronary arteries during acute coronary syndrome.

Objective: Compare ACS-related length of stay (LOS, total admission cost, and total admission cost by day of discharge/death for patients who died during an inpatient admission with a matched cohort discharged alive following an ACS-related inpatient stay. Methods: Medical and pharmacy claims (2009–2012 were used to identify admissions with a primary diagnosis of ACS from patients with at least 6 months of continuous enrollment prior to an ACS admission. Patients who died during their ACS admission (deceased cohort were matched (one-to-one to those who survived (survived cohort on age, sex, year of admission, Chronic Condition Index score, and prior revascularization. Mean LOS, total admission cost, and total admission cost by the day of discharge/death for the deceased cohort were compared with the survived cohort. A generalized linear model with log transformation was used to estimate the differences in the total expected incremental cost of an ACS admission and by the day of discharge/death between cohorts. A negative binomial model was used to estimate differences in the LOS between the two cohorts. Costs were inflated to 2013 dollars. Results: A total of 1,320 ACS claims from patients who died (n=1,320 were identified and matched to 1,319 claims from the survived patients (n=1,319.

    Objective The aim of this study was to assess the baseline clinical characteristics, coronary angiographic features, and adverse cardiovascular events during hospitalization and at 1 year of follow-up in obese patients compared with overweight and normal/underweight patients. Methods A prospective, multicenter study of consecutive patients undergoing percutaneous coronary intervention was performed. Results Of 2425 enrolled patients, 699 (28.8%) were obese, 1178 (48.6%) were overweight, and 548 (22.6%) were normal/underweight. Obese patients were more likely to be female and to have a higher prevalence of diabetes, hypertension, hypercholesterolemia, or previous percutaneous coronary intervention. Acute coronary syndrome was the indication for percutaneous coronary intervention in 77.0% of obese, 76.4% of overweight, and 77.4% of normal/underweight patients. No significant differences in the prevalence of multi-vessel coronary artery disease or multi-vessel percutaneous coronary intervention were found among the three groups. Additionally, no significant differences were found in stent thrombosis, readmission bleeding rates, or cardiac mortality among the three groups during hospitalization, at 1 month, and at 1 year. Conclusion The major adverse cardiovascular event rate was the same among the three groups throughout the study period. Accordingly, body mass index is considered a weak risk factor for cardiovascular comorbidities in Arab Jordanian patients.

    Full Text Available Aim. To compare effect of percutaneous balloon angioplasty (PCA and a systemic thrombolysis (STL on the central and intracardiac hemodynamics in patients with acute coronary syndrome (ACS with ST segment elevation.Material and methods. 80 patients with ACS with ST segment elevation were included in the study. Patients were split into 2 groups depending on reperfusion strategy. PCA was performed in 55 patients (first group. 25 patients of the second group had STL with Streptokinase, i/v, 1 500 000 units per hour. Echocardiography was performed in all patients at admission and after 3 and 7 days of treatment to evaluate intracardiac hemodynamics.Results. Both reperfusion methods significantly increase of ejection fraction (EF and maximal output speed of left ventricle (LV. Increase of LV EF in patients after PCA was higher than this in patients after STL. PCA improved LV diastolic function; STL did not change this characteristic. After PCA working diagnosis of ACS was transformed to the following final diagnosis: acute myocardial infarction (AMI with Q, AMI without Q and unstable angina in 37,5, 30,4 and 32,1% of patients, respectively. After STL diagnosis of AMI with Q was defined in all patients.Conclusion. PCA in patients with ACS with ST segment elevation results in fast improvement of global systolic and diastolic LV function. Besides, PCA prevents AMI with Q in a half of these patients.

    Full Text Available Management of anaphylaxis includes adrenaline, a life-saving drug, however appropriate dosing and administration are of crucial importance due to serious side effects. We present a 15-year-old female with anaphylactic reaction manifesting as acute coronary syndrome and pulmonary edema following the administration of adrenaline as an intravenous bolus. Focusing on anaphylaxis, adrenaline and coronary symptoms, this report discussed the interactions between three intertwining entities: Kounis syndrome, Takotsubo cardiomyopathy, and adrenaline-induced coronary vasospasm, and challenges in differential diagnosis. Brugada syndrome (cardiac autonomic dysfunction and clinical manifestation of the patient was also evaluated. Early consideration of adrenaline at the appropriate dose and administration route is essential in anaphylaxis management. Kounis syndrome should be considered in those presenting with allergy symptoms and chest pain and adrenaline should be used carefully due to possible risks of worsening coronary symptoms in patients with Kounis syndrome. This report also highlights a very rare side effect of adrenaline; the drug, which constitutes the cornerstone of anaphylaxis management, has a potential to trigger allergy itself due to metabisulfite-containing preservative.

    Full Text Available Significant left main coronary artery (LMCA stenosis is not rare and reported 3 to 10% of patients undergoing coronary angiography. Unprotected LMCA intervention is a still clinical challenge and surgery is still going to be a traditional management method in many cardiac centers. With a presentation of drug eluting stent (DES, extensive use of IVUS and skilled operators, number of such interventions increased rapidly which lead to change in recommendation in the guidelines regarding LMCA procedures in the stable angina (Class 2a recommendation for ostial and shaft lesion and class 2b recommendation for distal bifurcation lesion. However, there was not clear consensus about the management of unprotected LMCA lesion associated with acute myocardial infarction (MI with a LMCA culprit lesion itself or distinct culprit lesion of other major coronary arteries. Surgery could be preferred as an obligatory management strategy even in the high risk patients. With this review, we aimed to demonstrate treatment strategies of LMCA disease associated with acute coronary syndrome, particularly acute myocardial infarction (MI. In addition, we presented a short case series with LMCA lesion and ST elevated acute MI in which culprit lesion placed either in the left anterior descending artery or circumflex artery. We reviewed the current medical literature and propose simple algorithm for management.

  9. Stable coronary syndromes: pathophysiology, diagnostic advances and therapeutic need

    2018-01-01

    The diagnostic management of patients with angina pectoris typically centres on the detection of obstructive epicardial CAD, which aligns with evidence-based treatment options that include medical therapy and myocardial revascularisation. This clinical paradigm fails to account for the considerable proportion (approximately one-third) of patients with angina in whom obstructive CAD is excluded. This common scenario presents a diagnostic conundrum whereby angina occurs but there is no obstructive CAD (ischaemia and no obstructive coronary artery disease—INOCA). We review new insights into the pathophysiology of angina whereby myocardial ischaemia results from a deficient supply of oxygenated blood to the myocardium, due to various combinations of focal or diffuse epicardial disease (macrovascular), microvascular dysfunction or both. Macrovascular disease may be due to the presence of obstructive CAD secondary to atherosclerosis, or may be dynamic due to a functional disorder (eg, coronary artery spasm, myocardial bridging). Pathophysiology of coronary microvascular disease may involve anatomical abnormalities resulting in increased coronary resistance, or functional abnormalities resulting in abnormal vasomotor tone. We consider novel clinical diagnostic techniques enabling new insights into the causes of angina and appraise the need for improved therapeutic options for patients with INOCA. We conclude that the taxonomy of stable CAD could improve to better reflect the heterogeneous pathophysiology of the coronary circulation. We propose the term ‘stable coronary syndromes’ (SCS), which aligns with the well-established terminology for ‘acute coronary syndromes’. SCS subtends a clinically relevant classification that more fully encompasses the different diseases of the epicardial and microvascular coronary circulation. PMID:29030424

    Coronary artery aneurysm (CAA) is an uncommon clinical finding, with an incidence varying from 1.5%-4.9% in adults, and is usually considered a variant of coronary artery disease (CAD). CAA identified in the context of acute coronary syndrome (ACS) represents a unique management challenge, particularly if the morphology of the CAA is suspected to have provoked the acute clinical syndrome. CAA is associated with thrombus formation due to abnormal laminar flow, as well as abnormal platelet and endothelial-derived pathophysiologic factors within the CAA. Once formed, mural thrombus may potentiate the deposition of additional thrombus within aneurysmal segments. Percutaneous revascularization of CAA has been associated with complications including distal embolization of thrombus, no-reflow phenomenon, stent malapposition, dissection, and rupture. Presently, there are no formal guidelines to direct the management of CAA in patients presenting with ACS; controversies exist whether conservative, surgical, or catheter-based management should be pursued. In this manuscript, we present an extensive review of the existing literature and associated clinical guidelines, and propose a management algorithm for patients with this complex clinical scenario. Armed with this perspective, therapeutic decisions may be tailored to synthesize patient factors and preferences, individualized clinical assessment, and existing American Heart Association/American College of Cardiology guidelines for management of ACS.

    Full Text Available Fractional flow reserve (FFR assessment provides anatomical and physiological information that is often used to tailor treatment strategies in coronary artery disease. Whilst robust data validates FFR use in stable ischaemic heart disease, its use in acute coronary syndromes (ACS is less well investigated. We critically review the current data surrounding FFR use across the spectrum of ACS including culprit and non-culprit artery analysis. With adenosine being conventionally used to induce maximal hyperaemia during FFR assessment, co-existent clinical conditions may preclude its use during acute myocardial infarction. Therefore, we include a current review of instantaneous wave free ratio as a novel vasodilator independent method of assessing lesion severity as an alternative strategy to guide revascularisation in ACS.

    Full Text Available A 56-year-old woman with no medical history presented to the emergency department complaining of oppressive chest pain of three hours of duration triggered by walking. An electrocardiogram (ECG performed at hospital admission showed ST-segment depression and T-wave inversion in left precordial and inferior leads. Serum troponin I levels were above the normal values. Non ST-segment elevation acute coronary syndrome (NSTEACS was diagnosed and an invasive approach with a percutaneous coronary intervention was performed. No obstructive coronary lesions were observed. However a tortuous coronary fistula emerging from the left-anterior descending coronary artery to the pulmonary artery was observed. Coronary arterio-venous fistulas are present in 0.002% of the general population and in 0.25% of patients undergoing cardiac catheterization for any cause. Most of them are asymptomatic. Ischemic symptoms may develop but are infrequent in patients with no atherosclerotic disease.

    The purpose of the study was to compare the EASI system with the standard 12-lead surface electrocardiogram (ECG) for the accuracy in detecting the main electrocardiographic parameters (J point, PR, QT, and QRS) commonly monitored in patients with acute coronary syndromes or heart failure. In this observational comparative study, 253 patients who were consecutively admitted to the coronary care unit with acute coronary syndrome or heart failure were evaluated. In all patients, two complete 12-lead ECGs were acquired simultaneously. A total of 6,072 electrocardiographic leads were compared (3,036 standard and 3,036 EASI). No significant differences were found between the investigate parameters of the two measurement methods, either in patients with acute coronary syndrome or in those with heart failure. This study confirmed the accuracy of the EASI system in monitoring the main ECG parameters in patients admitted to the coronary care unit with acute coronary syndrome or heart failure.

    BACKGROUND/AIM. Adiponectin exerts profound protective actions during insulin resistence or prediabetes progression towards more severe clinical entities such as metabolic syndrome and/or cardiovascular disease. Since hypoadiponectinaemia contributes to the pathophysiology of the metabolic syndrome and coronary artery disease the level of circulating adiponectin may be an early marker of cardiovascular events. The aim of this study was to determine the relationships between serum adiponectin levels and parameters of both insulin sensitivity and obesity in patients with the metabolic syndrome and/or coronary artery disease, as well as to assess predictive value of adiponectin serum levels as a biomarker of these entitetis. The study included 100 patients with metabolic syndrome and/or coronary artery disease with different degree of insulin resistance and healthy, normoglycemic individuals. The control group comprising healthy, normoglycemic individuals was used for comparison. Serum level of adiponectin, fasting glucose, fasting insulinemia Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) index and anthropometric parameters were determined in all the subjects. Adiponectin was measured by using the ultrasensitive ELISA method. Insulinemia was measured by the radioimmunoassay (RIA) method. The presence of glycemic disorders was assessed on the basis of oral glucose tolerance test (OGTT). Results. Adiponectin level was inversely correlated with age (ρ = -0.015), parameters of both obesity (R = 0.437;p insulin resistance (R = 0.374; p insulin resistance. Most importantly, a statistically significant rapid decrease ih adiponectin was in the prediabetic stages (p < 0.01). The predictor value of adiponectin was 1,356.32 ± 402.65 pg/mL. The obtained resultats suggest that adiponectin may be a useful marker in identification of individuals with risk of developing metabolic syndrome and coronary artery disease, as well as a predictor of prediabetes.

    Full Text Available AIM: A potential link between infectious agents and atherosclerosis has been suggested. Data obtained from several seroepidemiological studies have suggested that infection with Chlamydophila pneumoniae, Helicobacter pylori, and Cytomegalovirus can initiate or maintain the atherosclerotic process. Aim of this study is to evaluate the probable relationship between serum titers of some various infectious agents and the development of acute coronary syndrome and to investigate the relationship between these infectious agents and other risk factors of acute coronary syndrome (smoking, hypertension, dyslipidemia, diabetes, and family history of CVD. METHOD: This is a hospital based case- control study was conducted on two groups: patients group included 86 patients, cases were collected from patients admitted to Cardiac Care Unit (CCU of Cleopatra hospital, and Ain Shams University hospital with acute myocardial infarction between January 2010 and June 2010 and control group included 86 apparently healthy individuals. A questionnaire was designed to determine conventional coronary artery risk factors. The sero-prevalence of Chlamydia pneumoniae (C. pneumoniae, Cytomegalovirus and Helicobacter pylori (H. pylori IgG antibodies were evaluated using quantitative enzyme-linked immunosorbent assay (ELISA. RESULTS: The results showed that there was an increased level of serum IgG antibodies of C. pneumoniae, Cytomegalovirus and Helicobacter pylori among patients with acute coronary syndrome compared to control subjects CONCLUSION: C. pneumoniae, Cytomegalovirus and Helicobacter pylori were expected to be predictors for the development of coronary artery disease, as there was significant elevation of the serum level of IgG antibodies against them.

    In recent years, acute coronary syndrome(ACS) has been getting more and more attentions. Radionuclide myocardial perfusion imaging (MPI) can make a quick accurate diagnosis for patients with acute chest pain who cann't be diagnosed by conventional methods. The sensitivity and negative predictive value of MPI are relatively high. Besides, MPI can be applicated in the detection of ischemic and infarct size and degree, the risk stratification and the assessment of prognosis of the patients with ACS, and the appraisal of the effect of strategies.

    Clinical presentation of viral myocarditis can mimic acute coronary syndrome and making diagnosis of viral heart disease (VHD) may be challenging. The presence of coronary artery disease (CAD) does not always exclude VHD and these entities can coexist. However, the incidence of co-occurrence of CAD and VHD is not precisely known. Moreover, inflammatory process caused by viruses may result in atherosclerotic plaque destabilization. The goal of this work is to summarize the current knowledge about co-occurrence of VHD and CAD. This article presents the importance of inflammatory process in both diseases and helps to understand pathophysiological mechanisms underlying their coexistence. It provides information about making differential diagnosis between these entities, including clinical presentation, noninvasive imaging features and findings in endomyocardial biopsy. Although currently there are no standard therapy strategies in coexistence of VHD and CAD, we present some remarkable aspects of treatment of patients, in whom VHD co-occurs with CAD. Viral heart disease may occur both in patients without and with atherosclerotic plaques in coronary arteries. Destabilization of atherosclerotic plaques in coronary arteries can be facilitated by inflammatory process. Increased inflammatory infiltrates in the coronary lesions of patients with VHD can lead to plaques' instability and consequently trigger acute coronary syndrome. In this article we attempted to present that co-occurrence of VHD and CAD may have therapeutic implications and as specific antiviral treatment is currently available, proper diagnosis and treatment can improve patient's condition and prognosis.

    Full Text Available OBJECTIVES: To describe the ERICO study (Strategy of Registry of Acute Coronary Syndrome, a prospective cohort to investigate the epidemiology of acute coronary syndrome. METHODS: The ERICO study, which is being performed at a secondary general hospital in São Paulo, Brazil, is enrolling consecutive acute coronary syndrome patients who are 35 years old or older. The sociodemographic information, medical assessments, treatment data and blood samples are collected at admission. After 30 days, the medical history is updated, and additional blood and urinary samples are collected. In addition, a retinography, carotid intima-media thickness, heart rate variability and pulse-wave velocity are performed. Questionnaires about food frequency, physical activity, sleep apnea and depression are also applied. At six months and annually after an acute event, information is collected by telephone. RESULTS: From February 2009 to September 2011, 738 patients with a diagnosis of an acute coronary syndrome were enrolled. Of these, 208 (28.2% had ST-elevation myocardial infarction (STEMI, 288 (39.0% had non-ST-elevation myocardial infarction (NSTEMI and 242 (32.8% had unstable angina (UA. The mean age was 62.7 years, 58.5% were men and 77.4% had 8 years or less of education. The most common cardiovascular risk factors were hypertension (76% and sedentarism (73.4%. Only 29.2% had a prior history of coronary heart disease. Compared with the ST-elevation myocardial infarction subgroup, the unstable angina and non-ST-elevation myocardial infarction patients had higher frequencies of hypertension, diabetes, prior coronary heart disease (p<0.001 and dyslipidemia (p = 0.03. Smoking was more frequent in the ST-elevation myocardial infarction patients (p = 0.006. CONCLUSIONS: Compared with other hospital registries, our findings revealed a higher burden of CV risk factors and less frequent prior CHD history.

    Full Text Available Abstract Kartagener syndrome consists of congenital bronchiectasis, sinusitis, and total situs inversus in half of the patients. A patient diagnosed with Kartagener syndrome was reffered to our department due to 3-vessel coronary disease. An off-pump coronary artery bypass operation was performed using both internal thoracic arteries and a saphenous vein graft. We performed a literature review for cases with Kartagener syndrome, coronary surgery and dextrocardia. Although a few cases of dextrocardia were found in the literature, no case of Kartagener syndrome was mentioned.

    Full Text Available Coronary computed tomography angiography (CCTA has evolved notably over the last decade, gaining an increased amount of temporo-spatial resolution in combination with decreased radiation exposure. The importance of CCTA is emerging especially in vulnerable and young patients who might not have developed a viable collateral vascular network to sustain the circulation to an infarction area during a major adverse coronary event. There are a few well-known markers by which a vulnerable plaque can be assessed and that can predict the subsequent events of sudden myocardial ischemia, such as an increased positive remodeling index (cut-off >1.4, low-attenuation plaque (cut-off 0.7, and napkin-ring sign (NRS. This manuscript presents a series of 3 clinical cases of young patients experiencing symptoms and signs of myocardial ischemia who underwent CCTA in order to assess the composition and functional characteristics of atherosclerotic plaques and their repercussion in developing an acute coronary syndrome.

    A 53-year-old woman was admitted to our chest pain unit because of an acute coronary syndrome (non ST-elevation myocardial infarction). She complained of asthma, chronic sinusitis and involuntary weight loss, occasional fever and night sweats over the past six months. Coronary angiography did not show any signs of macroscopic coronary artery disease, while echocardiography demonstrated a hemodynamically not significant pericardial effusion. Magnetic resonance imaging of the heart revealed a subendocardial scar, extension and localization pointing to a vascular genesis. Thoracic computed tomography revealed pulmonary opacities and blood tests showed an eosinophilia, leading to the clinical diagnosis of Churg-Strauss syndome. The patient responded quickly to oral steroids, and blood parameters returned to normal. Acute coronary syndrome in youngish patients without classical cardiovascular risk factors is suggestive for myocarditis but also for vasculitis. Churg-Strauss syndrome usually responds quickly to immunosuppressive therapy, associated with a rather good prognosis without high mortality. © Georg Thieme Verlag KG Stuttgart · New York.

    Abdominal obesity is an important cardiovascular risk factor. Therefore, identifying the best method for measuring waist circumference (WC) is a priority. To evaluate the eight methods of measuring WC in patients with acute coronary syndrome (ACS) as a predictor of cardiovascular complications during hospitalization. Prospective study of patients with ACS. The measurement of WC was performed by eight known methods: midpoint between the last rib and the iliac crest (1), point of minimum circumference (2); immediately above the iliac crest (3), umbilicus (4), one inch above the umbilicus (5), one centimeter above the umbilicus (6), smallest rib and (7) the point of greatest circumference around the waist (8). Complications included: angina, arrhythmia, heart failure, cardiogenic shock, hypotension, pericarditis and death. Logistic regression tests were used for predictive factors. A total of 55 patients were evaluated. During the hospitalization period, which corresponded on average to seven days, 37 (67%) patients had complications, with the exception of death, which was not observed in any of the cases. Of these complications, the only one that was associated with WC was angina, and with every cm of WC increase, the risk for angina increased from 7.5 to 9.9%, depending on the measurement site. It is noteworthy the fact that there was no difference between the different methods of measuring WC as a predictor of angina. The eight methods of measuring WC are also predictors of recurrent angina after acute coronary syndromes.

    Full Text Available Background. Acute coronary syndrome (ACS can complicate acute ischemic stroke, causing significant morbidity and mortality. To date, literatures that describe poststroke acute coronary syndrome and its morbidity and mortality burden are lacking. Methods. This is a single center, retrospective study where clinical characteristics, cardiac evaluation, and management of patients with suspected poststroke ACS were compared and analyzed for their association with inpatient mortality and 1-year all-cause mortality. Results. Of the 82 patients, 32% had chest pain and 88% had ischemic ECG changes; mean peak troponin level was 18, and mean ejection fraction was 40%. The medical management group had older individuals (73 versus 67 years, p<0.05, lower mean peak troponin levels (12 versus 49, p<0.05, and lower mean length of stay (12 versus 25 days, p<0.05 compared to those who underwent stent or CABG. Troponin levels were significantly associated with 1-year all-cause mortality. Conclusion. Age and troponin level appear to play a role in the current clinical decision making for patient with suspected poststroke ACS. Troponin level appears to significantly correlate with 1-year all-cause mortality. In the management of poststroke acute coronary syndrome, optimal medical therapy had similar inpatient and all-cause mortality compared to PCI and/or CABG.

    Early risk stratification in patients with non-ST elevation acute coronary syndromes (NSTE-ACS) is important since the benefit from more aggressive and costly treatment strategies is proportional to the risk of adverse clinical events. In the present study we assessed whether hybrid single photon emission computed tomography (SPECT)/coronary computed tomography angiography (CCTA) technology could be an appropriate tool in stratifying patients with NSTE-ACS. SPECT/CCTA was performed in 90 consecutive patients with NSTE-ACS. The Thrombolysis in Myocardial Infarction risk score (TIMI-RS) was used to classify patients as low- or high-risk. Imaging was performed using SPECT/CCTA to identify haemodynamically significant lesions defined as >50% stenosis on CCTA with a reversible perfusion defect on SPECT in the corresponding territory. CCTA demonstrated at least one lesion with >50% stenosis in 35 of 40 high-risk patients (87%) as compared to 14 of 50 low-risk patients (35%; TIMI-RS <3; p <0.0001). Of the 40 high-risk and 50 (16%) low-risk TIMI-RS patients, 16 (40%) and 8 (16%), respectively, had haemodynamically significant lesions (p = 0.01). Patients defined as high-risk by a high TIMI-RS, a positive CCTA scan or both (n = 45) resulted in a sensitivity of 95%, specificity of 49%, PPV of 35% and NPV of 97% for having haemodynamically significant coronary lesions. Those with normal perfusion were spared revascularization procedures, regardless of their TIMI-RS. Noninvasive assessment of coronary artery disease by SPECT/CCTA may play an important role in risk stratification of patients with NSTE-ACS by better identifying the subgroup requiring intervention.

    La prévalence des maladies cardiovasculaires connaît une croissance rapide dans les pays en développement, entraînant une incidence croissante du syndrome coronarien aigu (SCA. Les modalités de diagnostic et de traitement de cette maladie continuent d’évoluer, et il convient de tenir compte des ressources locales lors de la réalisation d’un diagnostic et la détermination des options thérapeutiques. Cet article constitue un guide à la prise en charge du SCA fondé sur l’expérience, et fournit des recommandations spécifiques destinées aux médecins hospitaliers travaillant dans les pays à bas et moyen revenu. Le diagnostic du SCA, y compris les SCA sans élévation du ST et avec élévation du ST, se concentre sur la stratification du risque, la vigilance relative aux manifestations subtiles ou atypiques, et la prise en considération d’autres causes des douleurs poitrinaires. Le processus de diagnostic implique l’évaluation des facteurs de risque, la connaissance des antécédents médicaux défavorables et les conclusions de l’examen physique (des variantes étant susceptibles d’exister dans les différentes populations, ainsi que l’utilisation de tests de diagnostic appropriés. Il est recommandé d’utiliser de l’aspirine à titre de traitement initial, parallèlement à un antiagrégant plaquettaire supplémentaire. Le prasugrel est préféré au clopidogrel si le patient présente un SCA avec élévation du ST et qu’une intervention coronaire percutanée (ICP est prévue. La bivalidurine devrait être le premier choix pour éviter la coagulation dans les SCA avec élévation du ST, suivie de l’enoxaparine (qui ne nécessite pas de perfusion, puis d’héparine non fractionnée. Pour les patients présentant un SCA sans élévation du ST et en cas de risque de saignement accru, le fondaparinux devrait être envisagé à la place de l’énoxaparine.

    Full Text Available Background: Acute Coronary Syndrome (ACS is a shift manifestations pattern of ischemic myocardium. Revascularization either with Primary Percutaneous Coronary Intervention (PCI or pharmacological therapy is an optional treatment for ST Elevation Acute Coronary Syndrome (STEACS patients. The aim of the study was to compare the functional capacity using six-minute walking test on STEACS patients who underwent Primary PCI or pharmacological therapy. Methods: A cross sectional study was conducted from September to October 2012 to 35 STEACS patients who were treated after two years. The samples were obtained from the list of patients at Dr. Hasan Sadikin General Hospital. Inclusion criteria consisted of patients diagnosed as STEACS, cooperative and not experiencing cognitive disturbance. The exclusion criteria were STEACS patients with unstable angina or myocardial infarct in the last month, stable exertional angina, and pregnant women. The patients underwent 6 minutes walking test,VO2max was measured using theCalahin and Cooper formula, then Metabolic Equation Task (METs was calculated. Data were analyzed by unpaired T-test. Results: There were 19 Primary PCI and 16 pharmacological therapy patients. The average of age between the two groups was distributed evenly. Most of the STEACS patients were male, had a college/academic degree and were retired. Patients treated with pharmacological therapy had higher average of VO2 max and METs than patients with Primary PCI. There was no significantly differences of METs between those groups (p>0.05 Conclusions: There were no significantly differences of functional capacity in STEACS patients treated with Primary PCI or Pharmacological therapy.

    Ticagrelor is the first reversibly binding oral P2Y12 receptor antagonist designed to reduce clinical thrombotic events in patients with acute coronary syndrome (ACS). Compared to clopidogrel, ticagrelor has been proven to significantly reduce the rate of death from vascular causes, myocardial infarction (MI), or stroke without an increase in the rate of overall major bleeding in patients who have an ACS with or without ST-segment elevation (STEMI and NSTEMI) or unstable angina (UA). To evaluate the cost-effectiveness and healthcare costs associated with secondary prevention of ACS using ticagrelor or clopidogrel in patients after STEMI, NSTEMI and UA. An economic model based on results from the PLATO trial was used to evaluate the cost-effectiveness of one-year therapy with ticagrelor or clopidogrel. The structure of the model consisted of two parts, i.e. the decision tree with one-year PLATO results and the Markov model with lifelong estimations, which exceeded PLATO follow-up data. The model was adjusted to Polish settings with country-specific data on death rates in the general population and direct medical costs calculated from the public payer's perspective. Costs were derived from the National Health Fund (NHF) and the Ministry of Health and presented in PLN 2013 values. Annual mean costs of second and subsequent years after stroke or MI were obtained from the literature. Uncertainty of assumed parameters was tested in scenarios and probabilistic sensitivity analyses. The adopted model allowed the estimation of an incremental cost-effectiveness ratio for life years gained (LYG) and an incremental cost-utility ratio for quality adjusted life years (QALY). Total direct medical costs to the public payer at a one year horizon were 2,905 PLN higher with ticagrelor than with clopidogrel. However, mean healthcare costs at a one year horizon (excluding drug costs and concomitant drugs) were 690 PLN higher for patients treated with clopidogrel. In a lifetime horizon

    2013-01-01

    Vascular Ehlers-Danlos syndrome is a rare connective tissue disorder associated with arterial dissection or rupture. Percutaneous coronary intervention (PCI) is often critical in patients with this syndrome because their coronary arteries are prone to dissection, enhancing the risk of stent borders dissection when conventional stent deployment pressures are used. Coronary artery bypass graft (CABG) treatment for these patients may also raise concerns because the left internal mammary artery is probably friable. Therefore, coronary artery revascularization in vascular Ehlers-Danlos syndrome either using PCI or CABG is challenging due to the arteries friability. A small number of cases have been published describing the friability of the vessels and associated complications; nevertheless, the optimum treatment remains unclear. We report the case of a 54-year-old woman treated successfully with PCI and CABG in two different acute coronary syndrome episodes, in which specific technical issues related to both procedures were decisive.

    Currently, cardiac computed tomography (CT) is increasingly being implemented into clinical algorithms, primarily due to substantial technical advances over the last decade. Its use in the setting of suspected acute coronary syndrome is of particular relevance, given the high degree of accumulating scientific evidence of improving patient outcomes. Performing cardiac CT requires specific knowledge on the available scan acquisitions and patient preparation. Also, expertise is required in order to interpret the coronary and extra-coronary findings adequately. The present article provides an overview of the different aspects on the use of cardiac CT in the setting of acute coronary syndrome.

    To explore the clinical significance the serum levels of N-Terminal proB-Type natriuretic peptide (NT-proBNP) and high-sensitivity C-reactive protein (hs-CRP) in patients with acute coronary syndrome,the serum levels of NT-proBNP and hs-CRP in patients and normal controls were determined by ECi Immunity Analyzer and radioimmunoassay respectively. The results showed that the serum levels of NT-proBNP and hs-CRP in patients with acute coronary syndrome were significantly higher than that of controls (P<0.05). The diagnostic specificity for acute coronary syndrome was 100% by combined detection of NT-proBNP and hs-CRP. The results suggest that the combined detection of serum NT-proBNP and hs-CRP levels are very important to evaluate heart function in patients with acute coronary syndrome. (authors)

    Coronary heart disease is the most common cause of death worldwide. In the United Kingdom in 2010, over 80,000 deaths were attributed to coronary heart disease, and one in 10 female deaths were due to coronary heart disease. Acute coronary syndrome, a subset of coronary heart disease, was responsible for 175,000 inpatient admissions in the United Kingdom in 2012. While men have traditionally been considered to be at higher risk of acute coronary syndrome, various studies have demonstrated that women often suffer from poorer outcomes following an adverse cardiovascular event. This gap is gradually narrowing with the introduction of advanced interventional strategies and pharmacotherapy. However, a better understanding of these differences is of crucial importance for the improvement of the pharmacological and interventional management of acute coronary syndrome and for the development of possible new gender-specific diagnostic and therapeutic options. The goals of this review are to evaluate gender differences in outcomes in patients with acute coronary syndrome in the current era and identify potential mechanisms behind these differences in outcomes following percutaneous coronary intervention.

    Burnout Syndrome is the extreme emotional response to chronic occupational stress, manifesting as physical and mental exhaustion. Although associated with higher prevalence of cardiovascular risk factors, no study so far has evaluated whether the Burnout Syndrome could be a prevalent factor in non-elderly individuals active in the labor market, admitted for acute coronary syndrome (ACS). To evaluate the prevalence of the Burnout Syndrome in non-elderly, economically active patients, hospitalized with ACS. Cross-sectional study conducted in a tertiary and private cardiology center, with economically active patients aged Burnout Syndrome was evaluated with the Burnout Syndrome Inventory (BSI), which assesses workplace conditions and four dimensions that characterize the syndrome: emotional exhaustion (EE), emotional distancing (EmD), dehumanization (De) and professional fulfillment (PF). The Lipp's Stress Symptoms Inventory for Adults (LSSI) was applied to evaluate global stress. Of 830 patients evaluated with suspected ACS, 170 met the study criteria, 90% of which were men, overall average age was 52 years, and 40.5% had an average income above 11 minimum wages. The prevalence of the Burnout Syndrome was 4.1%. When we evaluated each dimension individually, we found high EE in 34.7%, high De in 52.4%, high EDi in 30.6%, and low PF in 5.9%. The overall prevalence of stress was 87.5%. We found a low prevalence of Burnout Syndrome in an economically active, non-elderly population among patients admitted for ACS in a tertiary and private hospital.

    The outcome of patients with ST elevation acute coronary syndrome (ACS) has been increasingly improving in the general population over the past few decades. However, detailed analysis of the results show that the reduction in mortality rates is higher in males compared to their female counterparts. The excess mortality rate observed in women, though sometimes questioned, has been widely reported in the literature. The higher mortality rate observed in women with ST elevation ACS can be explained by the presence of aggravating clinical factors such as older age, a higher percentage of diabetics, and a higher frequency of cardiogenic shock. Other factors pertaining to patient management seem to negatively impact the outcome. These factors include a lower use of reperfusion strategies, longer time to treatment mainly as a result of diagnostic uncertainty with respect to a disease, which is believed to affect principally the male gender. The doubts that female patients themselves and their families have about the nature of their symptoms are also present in the medical environment but cease to exist in the catheterization laboratory. This is illustrated in the first clinical case that we present here. Coronary reperfusion is the cornerstone of the therapeutic management of MI. In this context, bleeding complications associated with the implemented treatments can also result in an increased mortality rate in this more vulnerable population. When all the factors likely to influence the prognosis are taken into account, excess mortality seems to persist in women, especially in younger patients. As described in the second clinical case, a distinct physio-pathological factor, more frequent in women, could account for this higher mortality rate. Indeed, spontaneous coronary dissection and intramural hematoma are not always easy to diagnose and may not be adequately managed by reperfusion treatments. In addition, these coronary reperfusion strategies are probably not adapted

    Full Text Available BACKGROUND Coronary heart disease has become an epidemic since 20th century. Deaths due to the same are increasing of around 17.5 million deaths in year 2012. The deaths are increasing more in developing countries and metabolic syndrome is a cluster of disorders, which are promoting the development of coronary artery diseases. The disorders include central obesity, insulin resistance, dyslipidaemia and hypertension. Increasing prevalence, changing lifestyle and progression of the disease without obvious symptoms had led to increasing morbidity and mortality. The non-infectious epidemic of the century is posing great challenges to healthcare and research in development of more infrastructure and funds to prevent and treat the disease. MATERIALS AND METHODS A total of 100 patients diagnosed with CAD and posted for Coronary Angiogram (CAG in ICCU at KIMS Hospital, Hubballi, were studied over a period of one and a half year. Cases were categorised according to ATPIII and new IDF criteria for metabolic syndrome and compared. Clinical evaluation, ECG, lipid profile and 2D-echo was done. Statistical analysis done using unpaired t-test, Mann-Whitney tests, Chi-square test and Kappa statistics. RESULTS Of the total 100, 57 had metabolic syndrome by either ATP criteria or IDF criteria. Kappa=0.859 (p-value 150 mg/dL and DM or FBS >100 mg/dL (p value <0.001. The mean values of SBP (144.0 vs. 120.8, DBP (85.6 vs. 73.8 and waist circumference (95.4 vs. 87.7 was statistically significant (p value <0.01 between patients with metabolic syndrome and without metabolic syndrome with IDF criteria (p value <0.001. It was observed LAD (28.1% was the most common vessel involved individually. There was no much significance related to metabolic syndrome. Incidence of CAD was more common in patients with metabolic syndrome than other group. CONCLUSION The prevalence of metabolic syndrome was high in patients with CAD. Both metabolic syndrome definitions identify subset

    Gender differences among patients with the acute coronary syndrome is still being debated, no research has been done on gender inequality among coronary syndrome patients in Sudan. To study gender differences in presentation, management, and outcomes of acute coronary syndrome in Sudan. This cross-sectional descriptive longitudinal study was conducted in Omdurman Teaching Hospital between July 2014 and August 2015. Patients were invited to sign a written informed consent form, were interviewed and examined by a physician, and then followed during their hospital stay. Information collected includes coronary risk factors, vital signs, echocardiography findings, arrhythmias, heart failure, cardiogenic shock, and death. The Ethical Committee of Omdurman Teaching Hospital approved the research. A total of 197 consecutive acute coronary syndrome patients were included, 43.1% were females. A significant statistical difference was evident between males and females regarding the type of acute coronary syndrome, its presentation, and time of presentation to the hospital, smoking, and receipt of thrombolysis (P 0.05). Women were less likely to receive thrombolytic therapy, present with chest pain, and diagnosed with ST-segment elevation myocardial infarction. No gender differences were found in acute coronary syndrome risk factors apart from smoking, which was more common in males, and there were no differences between males and females as regards in-hospital complications.

    To investigate the relationship between inflammatory factors and two Chinese medicine (CM) syndrome types of qi stagnation and blood stasis (QSBS) and qi deficiency and blood stasis (QDBS) in patients with acute coronary syndrome (ACS). Sixty subjects with ACS, whose pathogenesis changes belongs to qi disturbance blood stasis syndrome, were divided into 2 groups: 30 in the QSBS group and 30 in the QDBS group. The comparative analysis on them was carried out through comparing general information, coronary angiography and inflammatory factors including intracellular adhesion molecule-1 (ICAM-1), chitinase-3-like protein 1 (YKL-40) and lipoprotein-associated phospholipase A2 (Lp-PLA2). Compared with the QSBS group, Lp-PLA2 and YKL-40 levels in the QDBS group showed no-significant difference (P>0.05); ICAM-1 was significantly higher in the QDBS group than in the QSBS group in the pathological processes of qi disturbance and blood stasis syndrome of ACS (Psyndrome typing of QSBS and QDBS, which provides a research direction for standardization research of CM syndrome types.

    Acute coronary syndrome (ACS) is an important cause of mortality and morbidity in the general population. Recent advances in percutaneous coronary intervention (PCI) and optimal medical treatment have helped to improve the prognosis of patients with ACS. The previous reports indicated that women with ACS have a higher risk of adverse outcomes. However, sex differences in clinical outcomes with contemporary coronary revascularization and medical therapy for ACS have not been elucidated. We analyzed data from 676 consecutive patients with ACS (female, n = 166; male, n = 510) who were treated by emergency PCI between 2011 and 2014 at Juntendo Shizuoka Hospital. The patients were grouped according to sex. We defined major adverse cardiovascular events as a composite of all-cause death and ACS recurrence at 1 year and compared rates of major adverse cardiac events (MACE) between the groups. Women were older (75.4 ± 11.0 vs. 66.2 ± 12.2 years) and had a higher rate of multi-vessel disease, chronic kidney disease, and Killip IV at presentation. The cumulative rate of MACE at 1 year was significantly higher among women than men (17.5 vs. 10.2 %, p = 0.02, log-rank test). However, the association between women and a higher risk of MACE was attenuated after adjusting for age (HR 1.25, 95 % CI 0.77-2.00, p = 0.36) and other variables (HR 0.93, 95 % CI 0.36-2.44, p = 0.88). Adjustment for age and other risk factors attenuated sex differences in mid-term clinical outcomes among patients with ACS after emergency PCI.

    We report a case of Churg-Strauss syndrome (CSS) associated with coronary artery involvement, as demonstrated on coronary CT angiography (CCTA), without specific cardiac symptoms. A 69-year-old male had an 8-year history of bronchial asthma and chronic sinusitis with hypereosinophilia (35 %), polyneuropathy, and a positive antineutrophil cytoplasmic antibody titer, so he was diagnosed with CSS. The patient had no specific cardiac symptoms, but CCTA showed vasculitis and a saccular aneurysm involving the proximal coronary arteries. The 3-year follow-up CCTA demonstrated an increase in the extent of soft-tissue wall thickening and infiltration involving the coronary arteries. Although vasculitis of the major coronary arteries is not a prominent feature of CSS, our case suggests that the coronary arteries may also be targeted in this syndrome.

    Objective: To compare the accuracy of the Global Registry of Acute Coronary Events risk score and the Thrombolysis In Myocardial Infarction risk score in predicting the extent of coronary artery disease in patients with non-ST segment elevation acute coronary syndrome. Methods: The cross-sectional study comprising 406 consecutive patients was conducted at the National Institute of Cardiovascular Diseases, Karachi, from August 2010 to March 2011. For all patients, the GRACE and TIMI RS's relevant scores on the two indices were calculated on admission using specified variables. The patients underwent coronary angiography to determine the extent of the disease. A significant level was defined as >70% stenosis in any major epicardial artery or >50% stenosis in the left main coronary artery. SPSS 19 was used for statistical analysis. Results: Both the indices showed good predictive value in identifying the extent of the disease. A Thrombolysis In Myocardial Infarction score >4 and Global Registry of Acute Coronary Events score >133 was significantly associated with 3vessel disease and left main disease, while for the former score <4 and latter score <133 was associated with normal or non-obstructive coronary disease (p<0.01). On comparison of the two risk scores, the discriminatory accuracy of the latter was significantly superior to the former in predicting 2vessel, 3vessel and left main diseases (p<0.05). Conclusion: Although both the indices were helpful in predicting the extent of the disease, the Global Registry showed better performance and was more strongly associated with multi-vessel and left main coronary artery disease.

    Full Text Available Cardiac tumors can be primary or metastatic, the latter being more frequent and usually of pulmonary or hematologic origin. These patients’ clinical signs are non-specific and the electrocardiogram (ECG can assume many patterns, among which, ST-segment elevation. Nevertheless, associated occlusion of the coronary arteries is rare in these situations.We present a 79-year-old woman with a history of pulmonary neoplasia who was admitted to the emergency department due to atypical chest pain, cough and worsening dyspnea in the previous 3 days. The ECG revealed an ST-segment elevation in the anterolateral and inferolateral leads, despite normal blood work, namely normal troponin. Due to the disparity between the patient’s symptoms and the ECG findings, a decision was made not to proceed to primary angioplasty, but to further investigate with echocardiography, which revealed a mass localized in the anterolateral and inferolateral left ventricle walls, confirmed by computed tomography. The patient was admitted in the medical ward for symptomatic management. Her clinical condition gradually deteriorated due to the disease’s natural evolution and she died two weeks later.This case highlights the importance to keep in mind differential diagnoses to acute coronary syndromes, when a ST-segment elevation is encountered on an ECG.

    Full Text Available Arterial chronic hypertension (HTN is a well-known cardiovascular risk factor for development of atherosclerosis. In order to explain the relation between HTN and acute coronary syndromes the following factors should be considered: (1 risk factors are shared by the diseases, such as genetic risk, insulin resistance, sympathetic hyperactivity, and vasoactive substances (i.e., angiotensin II; (2 hypertension is associated with the development of atherosclerosis (which in turn contributes to progression of myocardial infarction. From all the registries and the data available up to now, hypertensive patients with ACS are more likely to be older, female, of nonwhite ethnicity, and having a higher prevalence of comorbidities. Data on the prognostic role of a preexisting hypertensive state in ACS patients are so far contrasting. The aim of the present paper is to focus on hypertensive patients with ACS, in order to better elucidate whether these patients are at higher risk and deserve a tailored approach for management and followup.

    Matrix metalloproteinases (MMPs) are a family of zinc metallo-endopeptidases secreted by cells and are responsible for much of the turnover of matrix components. Several studies have shown that MMPs are involved in all stages of the atherosclerotic process, from the initial lesion to plaque rupture. Recent evidence suggests that MMP activity may facilitate atherosclerosis, plaque destabilization, and platelet aggregation. In the heart, matrix metalloproteinases participate in vascular remodeling, plaque instability, and ventricular remodelling after cardiac injury. The aim of the present article is to review the structure, function, regulation of MMPs and to discuss their potential role in the pathogenesis of acute coronary syndromes, as well as their contribution and usefullness in the setting of the disease.

    The objective of this review was to summarize evidence gathered for the prognostic value of routine and novel blood lipids and lipoproteins measured in patients with acute coronary syndromes (ACS). Data supports clear association with risk and actionable value for non-high-density lipoprotein (Non-HDL) cholesterol and plasma ceramides in a setting of ACS. The prognostic value and clinical actionability of apolipoprotein B (apoB) and lipoprotein(a) [Lp(a)] in ACS have not been thoroughly tested, while the data for omega-3 fatty acids and oxidized low-density lipoprotein (Ox-LDL) are either untested or more varied. Measuring basic lipids, which should include Non-HDL cholesterol, at the time of presentation for ACS is guideline mandated. Plasma ceramides also provide useful information to guide both treatment decisions and follow-up. Additional studies targeting ACS patients are necessary for apoB, Lp(a), omega-3 fatty acids, and Ox-LDL.

    Previous studies have examined risk factors for the development of heart failure (HF) subsequent to acute coronary syndrome (ACS). Our study seeks to clarify the clinical variables that best characterize patients who remain free from HF after coronary artery bypass grafting (CABG) surgery for ACS to determine novel biological factors favouring freedom from HF in prospective translational studies. Nova Scotia residents (1995-2012) undergoing CABG within 3 weeks of ACS were included. The primary outcome was freedom from readmission to hospital due to HF. Descriptive statistics were generated, and a Cox proportional hazards model assessed outcome with adjustment for clinical characteristics. Of 11 936 Nova Scotians who underwent isolated CABG, 3264 (27%) had a recent ACS and were included. Deaths occurred in 210 (6%) of subjects prior to discharge. A total of 3054 patients were included in the long-term analysis. During follow-up, HF necessitating readmission occurred in 688 (21%) subjects with a hazard ratio of 12% at 2 years. The adjusted Cox model demonstrated significantly better freedom from HF for younger, male subjects without metabolic syndrome and no history of chronic obstructive pulmonary disease, renal insufficiency, atrial fibrillation, or HF. Our findings have outlined important clinical variables that predict freedom from HF. Furthermore, we have shown that 12% of patients undergoing CABG after ACS develop HF (2 years). Our findings support our next phase in which we plan to prospectively collect blood and tissue specimens from ACS patients undergoing CABG in order to determine novel biological mechanism(s) that favour resolution of post-ACS inflammation. © 2017 The Authors.

    Since identification of aspartate aminotransferase as the first cardiac biomarker in the 1950s, there have been a number of new markers used for myocardial damage detection over the decades. There have also been several generations of troponin assays, each with progressively increasing sensitivity for troponin detection. Accordingly, the "standard of care" for myocardial damage detection continues to change. The purpose of this paper is to review the clinical utility, biological mechanisms, and predictive value of these various biomarkers in contemporary clinical studies. As of this writing, a fifth "next" generation troponin assay has now been cleared by the US Food and Drug Administration for clinical use in the USA for subjects presenting with suspected acute coronary syndromes. Use of these high-sensitivity assays has allowed for earlier detection of myocardial damage as well as greater negative predictive value for infarction after only one or two serial measurements. Recent algorithms utilizing these assays have allowed for more rapid rule-out of myocardial infarction in emergency department settings. In this review, we discuss novel assays available for the risk assessment of subjects presenting with chest pain, including both the "next generation" cardiac troponin assays as well as other novel biomarkers. We review the biological mechanisms for these markers, and explore the positive and negative predictive value of the assays in clinical studies, where reported. We also discuss the potential use of these new markers within the context of future clinical care in the modern era of higher sensitivity troponin testing. Finally, we discuss advances in new platforms (e.g., mass spectrometry) that historically have not been considered for rapid in vitro diagnostic capabilities, but that are taking a larger role in clinical diagnostics, and whose prognostic value and power promise to usher in new markers with potential for future clinical utility in acute coronary

    Ticagrelor is an orally administered antiplatelet agent used to reduce thrombotic events in patients with acute coronary syndromes. Data from two studies in patients with acute coronary syndromes with large amounts of pharmacokinetic (PK) data (phase IIb DISPERSE-2 study (n = 609)); phase III PLATO PK substudy (n = 6,381)), along with non-linear mixed effects modeling software, were used to develop population PK models for ticagrelor and its metabolite, AR-C124910XX, and to evaluate the impact of demographic and clinical factors on the PK of ticagrelor and AR-C124910XX. 32 covariates relating to disease history, biomarkers, clinical chemistry, and concomitant medications were assessed. A one-compartment model with population mean PK parameters of firstorder absorption rate constant (0.67/h), apparent systemic clearance (14 L/h), and apparent volume of distribution (221 L) was shown to best describe the PK profile of ticagrelor. Patients co-administered moderate CYP3A inducers or inhibitors increased (by 110%, 95% confidence interval (CI), 52 - 192%) or decreased (by 64%, 95% CI, 39 - 73%) apparent ticagrelor clearance, respectively, while habitual smoking decreased apparent ticagrelor clearance by 22% (95% CI, 19 - 25%). Ticagrelor bioavailability was 21% (95% CI, 19 - 22%) lower at treatment initiation (visit 1) versus subsequent visits. Compared with Caucasian patients, ticagrelor bioavailability was 39% (95% CI, 33 - 46%) higher in Asian patients and 18% (95% CI, 6 - 28%) lower in Black patients. In the current analyses, the population PK models developed for ticagrelor and AR-C124910XX described the data obtained in the DISPERSE-2 and PLATO studies well, and were consistent with previous phase I PK studies.

    Full text: In the cardiac emergency department, a number of patients present with acute chest pain. In case of non diagnostic ECG and enzymes, accurately categorizing the patient in high and low probability is difficult. Aim of study was to evaluate the role of resting myocardial perfusion imaging (MPI) in patients with acute coronary syndrome (ACS) and then to compare the results with subsequent stress imaging. Material and Methods. A total of 34 patients were selected for the study, which were divided into three groups on the basis of respective probabilities of having ACS. This probability was decided on the basis of nature of chest pain, ECG findings, enzymes levels, and age and sex. Arbitrary score was given to patient's condition. This score ranged from 1 to 14. Patients with score between 1-6 were assigned low probability, from 7-10 were assigned intermediate probability and patients having score greater than 11 were placed in high probability groups. Patients in the low and intermediate probability groups were injected with Tc 99 m- MIBI within 6 hours of onset of chest pain and were undergone resting myocardial perfusion imaging (MPI) 3 to five hours after injection.. Imaging in high probability group was performed at discharge. Four weeks after the acute event all the patients underwent stress myocardial perfusion imaging. Results: All patients (100%) with low probability of ACS (n=10) showed negative resting scans. On stress MPI two patients (20%) showed new defects. Patient with high probability of ACS (n=12), all were positive 100% on resting MPI. On stress MPI, three showed (25%) no change from rest MPI, while nine patients (75%) showed augmentation of defects and four out of these nine patients (33%) also showed new perfusion defects. Patients with intermediate probability of ACS (n=12), three showed positive rest MPI (25%). On stress MPI out of these three cases, one showed (8%) no change from rest MPI and two showed (17%) augmentation of defect

Materials and methods. This study included all patients admitted to the Cardiology Department of the Clinical Hospital № 2 Lyubertsy with a diagnosis of ACS. All the patients were asked to complete a questionnaire on assessing adherence during their stay in hospital. Results. Under obtain preliminary results (six months from the start of the study the study included 130 patients with ACS: 79 men and 51 women. Half of the patients (n = 61 are constantly observed by a doctor, and the other half almost did not seek for medical help. According to the Moriscos–Green test 71 persons (54.6 % were adherented to medical treatment, 55 patients were found to have low adherence to therapy. Only 42 patients, one-third of the survey participants took all drugs recommended by the doctor . Less than 9 % of patients hospitalized with diagnosis of ACS took statins, one third of patients were recommended to take aspirin. Primary cause of recommendations for medical therapy is forgetfulness (18.5 %, about 10 % of patients are afraid of the side effects of drugs. The main way to improve patient adherence to therapy was mentioned like information from the doctor about the possibility of improving the life and disease prognosis (62.3 %, quality of life, improving well-being(25.8 %, only 4 patients (3 % were totally unwilling to comply with medical recommendations. Conclusion. Specially designed questionnaire gave possibility to assess a number of facts (very low prescription of some of the main groups of cardiac drugs, high mortality identified in the study of the, and their possible causes. In addition to the personal factors of patients (forgetfulness, the main causes of poor adherence to treatment is the lack of awareness of patients about their illness, the possibilities of modern therapy

    Acute Coronary Syndrome (ACS) is used to describe the spectrum of coronary artery disease (CAD). Troponin T is the determinant of the most sensitive marker of ACS, but there aren’t all hospitals have this because of expensiveness. Mean Platelet Volume (MPV) is one of the components of a complete blood routine examination and relatively cheap as a marker in ACS. Determining the sensitivity and specificity of MPV in detecting cases of the acute coronary syndrome, 325 subjects’ medical records were from the period of July 2013 to June 2014; 228 ACS patients met the inclusion criteria. 228 subjects showed a risk factor for age ≥45years of more 195 (85.5%). 122 subjects with hypertension (53.5%) and subjects who smoked 118 (51.8%) that suffered most ACS. Subjects with risk factors for diabetes mellitus, obesity, menopause and dyslipidemia in this study was lower than non-diabetic 161 (70.6%), obese189 (82.9%), nonmenopause 196 (86%) and normal lipid 210 (92.1%). But there was norelation between risk factor with MPV and troponin T statistically. The results of diagnostic tests MPV for the evaluation of patients with ACS, sensitivity 92%, specificity 71%, positive predictive value 95% and negative predictive value 58%.

    To evaluate the efficiency and safety of emergency department (ED) coronary computed tomography angiography (CTA) during a 3-year clinical experience. Single-center registry of coronary CTA in consecutive ED patients with suspicion of acute coronary syndrome (ACS). The primary outcome was efficiency of coronary CTA defined as the length of hospitalization. Secondary endpoints of safety were defined as the rate of downstream testing, normalcy rates of invasive coronary angiography (ICA), absence of missed ACS, and major adverse cardiac events (MACE) during follow-up, and index radiation exposure. One thousand twenty two consecutive patients were referred for clinical coronary CTA with suspicion of ACS. Overall, median time to discharge home was 10.5 (5.7-24.1) hours. Patient disposition was 42.7 % direct discharge from the ED, 43.2 % discharge from emergency unit, and 14.1 % hospital admission. ACS rate during index hospitalization was 9.1 %. One hundred ninety two patients underwent additional diagnostic imaging and 77 underwent ICA. The positive predictive value of CTA compared to ICA was 78.9 % (95 %-CI 68.1-87.5 %). Median CT radiation exposure was 4.0 (2.5-5.8) mSv. No ACS was missed; MACE at follow-up after negative CTA was 0.2 %. Coronary CTA in an experienced tertiary care setting allows for efficient and safe management of patients with suspicion for ACS. (orig.)

    The incidence of depression and anxiety is higher in patients with acute coronary syndrome. The aim of this study is to determine whether experiencing acute coronary syndrome prior to open heart surgery affects patients in terms of depression, hopelessness, anxiety, fear of death and quality of life. The study included 63 patients who underwent coronary bypass surgery between January 2015 and January 2016. The patients were divided into two groups: those diagnosed after acute coronary syndrome (Group 1) and those diagnosed without acute coronary syndrome (Group 2). Beck depression scale, Beck hopelessness scale, Templer death anxiety scale and death depression scale, State-Trait anxiety inventory and WHOQOL-Bref quality of life scale were applied. There was no significant difference between the two groups in terms of the total score obtained from Beck depression scale, Beck hopelessness scale - future-related emotions, loss of motivation, future-related expectations subgroups, death anxiety scale, the death depression scale, State-Trait Anxiety Inventory - social and environmental subgroups. The mental quality of life sub-scores of group 2 were significantly higher. The patients in both groups were found to be depressed and hopeless about the future. Anxiety levels were found to be significantly higher in all of the patients in both groups. Acute coronary syndrome before coronary artery bypass surgery impairs more the quality of life in mental terms. But unexpectedly there are no differences in terms of depression, hopelessness, anxiety and fear of death.

The aim of the study is to evaluate the impact of RCA on CIN (increase in serum creatinine ≥0.5 mg/dL or ≥25% after an acute coronary syndrome. Methods: From April to September 2016, patients suffering acute coronary syndromes who underwent diagnostic coronary angiography, with the possibility of ad hoc coronary angioplasty, were prospectively enrolled. At the operator's discretion, patients underwent RCA or conventional coronary angiography (CCA. CIN (primary endpoint, as well as analytical, angiographic and clinical endpoints, were compared between groups. Results: Of the 235 patients enrolled, 116 patients received RCA and 119 patients received CCA. The RCA group was composed of older patients (64.0 ± 11.8 years vs. 59.7 ± 12.1 years; p = 0.006, a higher proportion of women (44.8 vs. 17.6%; p < 0.001, patients with a lower estimated glomerular filtration rate (76 ± 25 vs. 86 ± 27 ml/min/1.73 m2; p = 0.001, and patients who underwent fewer coronary angioplasties (p < 0.001 compared with the CCA group.

    Coronary collateral growth (CCG) is impaired in metabolic syndrome (MetS). microRNA-145 (miR-145-Adv) delivery to our rat model of MetS (JCR) completely restored and neutrophil depletion significantly improved CCG. We determined whether low endogenous levels of miR-145 in MetS allowed for elevated production of 20-hydroxyeicosatetraenoic acid (20-HETE), which, in turn, resulted in excessive neutrophil accumulation and endothelial dysfunction leading to impaired CCG. Rats underwent 0-9 days of repetitive ischemia (RI). RI-induced cardiac CYP4F (neutrophil-specific 20-HETE synthase) expression and 20-HETE levels were increased (4-fold) in JCR vs. normal rats. miR-145-Adv and 20-HETE antagonists abolished and neutrophil depletion (blocking antibodies) reduced (~60%) RI-induced increases in CYP4F expression and 20-HETE production in JCR rats. Impaired CCG in JCR rats (collateral-dependent blood flow using microspheres) was completely restored by 20-HETE antagonists [collateral-dependent zone (CZ)/normal zone (NZ) flow ratio was 0.76 ± 0.07 in JCR + 20-SOLA, 0.84 ± 0.05 in JCR + 20-HEDGE vs. 0.11 ± 0.02 in JCR vs. 0.84 ± 0.03 in normal rats]. In JCR rats, elevated 20-HETE was associated with excessive expression of endothelial adhesion molecules and neutrophil infiltration, which were reversed by miR-145-Adv. Endothelium-dependent vasodilation of coronary arteries, endothelial nitric oxide synthase (eNOS) Ser1179 phosphorylation, eNOS-dependent NO ·- production and endothelial cell survival were compromised in JCR rats. These parameters of endothelial dysfunction were completely reversed by 20-HETE antagonism or miR-145-Adv delivery, whereas neutrophil depletion resulted in partial reversal (~70%). We conclude that low miR-145 in MetS allows for increased 20-HETE, mainly from neutrophils, which compromises endothelial cell survival and function leading to impaired CCG. 20-HETE antagonists could provide viable therapy for restoration of CCG in MetS.

    The prevalence of coronary artery disease is on the rise as the life expectancy of the population increases. However, treatment of acute coronary syndrome in the elderly patients has its own problems that have not been thoroughly addressed in the clinical trials. Since these patients are generally fragile and have multiple co-morbidities, the course of acute coronary syndrome can frequently be complicated. Infection, which co-exists either at the initial presentation or is acquired during the hospital stay, is a condition about which there is little published data. Therefore, in our study, we wanted to assess the impact of infection on mortality in octogenarians who have acute coronary syndrome METHODS: We retrospectively analyzed the data of 174 octogenarians who had been admitted to the coronary care unit with acute coronary syndrome. All-cause mortality was defined as the primary endpoint of the study. Overall 53 octogenarian patients (30.5%) had an infection along with acute coronary syndrome. The mean duration of follow-up was 10 months (1-25 months). Both in-hospital and long-term mortality were higher in these patients (18.9% vs 6.6%, p = 0.01; 52.8% vs 27.5%, p < 0.01; respectively). Kaplan-Meier analysis also showed lower cumulative survival. (p [log-rank] = 0.002). In multivariate Cox regression analysis; undergoing coronary angiography, infection (HR 1.96, 95% CI 1.15-3.34, p = 0.01), left ventricular ejection fraction and maximum C reactive protein levels were found as independent predictors of long-term survival. Infection in octogenarians who were admitted due to acute coronary syndrome was frequent and increased their mortality substantially. Copyright © 2018 Elsevier B.V. All rights reserved.

    Noonan syndrome is a constellation of congenital malformations including heart defects, facial anomalies and short stature. The cardiovascular defects are variable and extensive, with the most common being pulmonary stenosis and hypertrophic cardiomyopathy. Coronary artery anomalies have only been reported in a few cases. We report a child with Noonan syndrome status post pulmonary stenosis and atrial septal defect repair, who developed bilateral coronary artery aneurysms. The aneurysms were diagnosed with both cardiac magnetic resonance imaging and coronary computed tomography angiography. There had been no evidence of them on a cardiac MR exam 5 years previously.

    Over the past two decades, the use of multiple biomarkers has changed cardiovascular disease management. Recently, several trials have assessed the diagnostic and prognostic performances of copeptin, especially in patients with heart failure or acute coronary syndromes. Primary results are interesting, with copeptin looking promising for: the management of patients who present at emergency departments early after chest pain onset and the risk stratification of patients with heart failure. The purpose of this article is to review the data on the place of copeptin in the management of patients with chest pain or heart failure. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Polycystic ovary syndrome (PCOS), a common endocrine disorder of reproductive-aged women, is associated with multiple risk factors for coronary heart disease (CHD), such as diabetes mellitus, dyslipidemia, visceral obesity, and hypertension. However, premature coronary atherosclerosis has not been demonstrated in PCOS women. Electron beam computed tomography (EBCT) noninvasively measures coronary artery calcium (CAC), a marker for coronary atherosclerosis. We measured CAC by EBCT in 30- to 45-yr-old premenopausal PCOS women and compared the results to CAC in 1) recruited normal ovulatory volunteers matched for age and weight to the PCOS cohort, and 2) community-dwelling women of similar age in an extant coronary calcium database. Healthy, community-dwelling, ovulatory controls (n = 71) were matched by age and body mass index (BMI) to PCOS women (n = 36). Women with diabetes or known CHD were excluded. Subjects underwent EBCT scanning, oral glucose tolerance testing, and CHD risk factor assessment. PCOS women had significantly higher levels of serum total and low density lipoprotein cholesterol and testosterone levels than matched controls. PCOS and control women were obese and had a greater mean BMI than community-dwelling women (33 kg/m(2) for PCOS vs. 31 kg/m(2) for control; P PCOS women (39%) than in matched controls (21%; odds ratio, 2.4; P = 0.05) or community-dwelling women (9.9%; odds ratio, 5.9; P PCOS women than in obese or nonobese women of similar age. PCOS women are at increased risk for atherosclerosis and should be targeted for primary prevention of CHD.

    Background Utilization of cardiac rehabilitation is suboptimal. The aim of the study was to assess referral trends over the past decade, to identify predictors for referral to a cardiac rehabilitation program, and to evaluate the association with one-year mortality in a large national registry of acute coronary syndrome patients. Design and methods Data were extracted from the Acute Coronary Syndrome Israeli Survey national surveys between 2006-2013. A total of 6551 patients discharged with a diagnosis of acute coronary syndrome were included. Results Referral to cardiac rehabilitation following an acute coronary syndrome increased from 38% in 2006 to 57% in 2013 ( p for trend acute coronary syndrome. However, cardiac rehabilitation is still under-utilized in important high-risk subsets of this population. Patients referred to cardiac rehabilitation have a lower adjusted mortality risk.

    Congestive heart failure (CHF) is a common and preventable complication of acute coronary syndrome (ACS). Nevertheless, ACS risk scores have not been shown to predict CHF risk. We investigated whether the at-discharge Global Registry of Acute Coronary Events (GRACE) score predicts heart failure admission following ACS. Five-year mortality and hospitalization data were obtained for patients admitted with ACS from June 1999 to September 2009 to a single centre of the GRACE registry. CHF was defined as any admission assigned WHO International Classification of Diseases 10 diagnostic code I50. The hazard ratio (HR) for CHF according to GRACE score was estimated in Cox models adjusting for age, gender and the presence of CHF on index admission. Among 1,956 patients, CHF was recorded on index admission in 141 patients (7%), and 243 (12%) were admitted with CHF over 3.8 median years of follow-up. Compared to the lowest quintile, patients in the highest GRACE score quintile had more CHF admissions (116 vs 17) and a shorter time to first admission (1.2 vs 2.0 years, HR 9.87, 95% CI 5.93-16.43). Per standard deviation increment in GRACE score, the instantaneous risk was more than two-fold higher (HR 2.28; 95% CI 2.02-2.57), including after adjustment for CHF on index admission, age and gender (HR 2.49; 95% CI 2.06-3.02). The C-statistic for CHF admission at 1-year was 0.74 (95% CI 0.70-0.79). The GRACE score predicts CHF admission, and may therefore be used to target ACS patients at high risk of CHF with clinical monitoring and therapies. © The European Society of Cardiology 2014.

    Vitamin D deficiency has been consistently linked with cardiovascular diseases. However, results of intervention studies are contradictory. The aim of this study was to evaluate the effect of treatment with calcifediol (25(OH)D 3 ) on the cardiovascular system of patients with non-ST-elevation acute coronary syndrome after percutaneous coronary intervention. A prospective study assessing≥60-year-old patients with non-ST-elevation acute coronary syndrome, coronary artery disease and percutaneous revascularisation. We randomly assigned 41 patients (70.6±6.3 years) into 2 groups: Standard treatment+25(OH)D 3 supplementation or standard treatment alone. Major adverse cardiovascular events (MACE) were evaluated at the conclusion of the 3-month follow-up period. 25(OH)D levels were analysed with regard to other relevant analytical variables and coronary disease extent. Basal levels of 25(OH)D≤50nmol/L were associated with multivessel coronary artery disease (RR: 2.6 [CI 95%:1.1-7.1], P=.027) and 25(OH)D≤50nmol/L+parathormone ≥65pg/mL levels correlated with increased risk for MACE (RR: 4 [CI 95%: 1.1-21.8], P=.04]. One MACE was detected in the supplemented group versus five in the control group (P=.66). Among patients with 25(OH)D levels≤50nmol/L at the end of the study, 28.6% had MACE versus 0% among patients with 25(OH)D>50nmol/L (RR: 1,4; P=.037). Vitamin D deficiency plus secondary hyperparathyroidism may be an effective predictor of MACE. A trend throughout the follow up period towards a reduction in MACE among patients supplemented with 25(OH)D 3 was detected. 25(OH)D levels≤50nmol/L at the end of the intervention period were significantly associated with an increased number of MACE, hence, 25(OH)D level normalisation could improve cardiovascular health in addition to bone health.

    Multislice computed tomography (MSCT) was used to evaluate coronary artery remodeling in patients with acute coronary syndrome (ACS) and stable angina (SA). MSCT was performed in 31 patients with ACS and 26 patients with SA and intravascular ultrasound (IVUS) was performed in 28 of these 57 patients. In both the MSCT and IVUS analyses, coronary artery remodeling was assessed by the remodeling index (RI): RI>1.10 was defined as positive coronary artery remodeling (PCAR) and RI<0.95 was defined as negative coronary artery remodeling (NCAR). The RI assessed by MSCT closely correlated with that of IVUS (r=0.86, n=28). The vessel area at the region of maximum luminal narrowing was also comparable between the MSCT and IVUS measurements (r=0.92). PCAR was present in 19 patients (61.3%) with ACS, but in none of the patients with SA (p<0.0001). However, NCAR was present in only 1 patient with ACS (3.2%), but was present in 18 patients (62.9%) with SA. The RI was significantly larger in patients with ACS (1.19±0.18) than in those with SA (0.89±0.10, p<0.0001). MSCT accurately assesses coronary artery remodeling. (author)

The study was aimed at measuring the associations between elevated serum neopterin and increased risk of cardiovascular (CV events in ACS. METHODS: This was a prospective cohort study, recruited 71 ACS patients from January 31 through August 31, 2007 in Sanglah Hospital of Udayana School of Medicine, Denpasar, Bali. Cardiovascular events, such as: CV death, recurrent myocardial infarction, stroke and recurrent myocardial ischemia were previously defined. Relative risk and survival rate were measured successively by Cox proportional model and Kaplan-Meier curve. RESULTS: Of 71 ACS patients aged 56.8±9.5 years, 21 (29.5% subjects underwent CV events. Overall mean followup was 151.6 (95% CI: 129.7-173.5 days. Baseline characteristic were similarly distributed between groups with the highest quartile neopterin level (≥14.7 nmol/L than those with lowest quartile (≤6.2 nmol/L. Patients with the highest quartile had the worst survival curve than those with the lowest quartile (log-rank test; p=0.047. On Cox proportional model, relative risk of highest quartile group was 5.84 (95% CI: 1.19-28.47; p=0.029 compared to lowest quartile, after being adjusted with other predictors. CONCLUSIONS: Elevated serum neopterin is associated with increased risk of CV events in acute coronary syndromes. KEYWORDS: neopterin, cardiovascular events, acute coronary syndromes.

    Full Text Available Objective: To analyze the effect of preoperative small dose of tirofiban on PCI treatment prognosis in patients with acute coronary syndrome. Methods: A total of 108 cases with acute coronary syndrome who received PCI treatment in our hospital from August 2011 to May 2014 were included for study and randomly divided into observation group and control group by half according to different treatment methods. Control group received PCI treatment alone, observation group received small dose of tirofiban combined with PCI treatment, and then differences in hemorheology indicators, platelet function, left ventricular systolic function and left ventricular diastolic function parameters, serum indicators and so on were compared between two groups after treatment. Results: Whole blood high shear viscosity, whole blood low shear viscosity, reduced high shear viscosity, reduced low shear viscosity, plasma ratio viscosity, erythrocyte aggregation index and erythrocyte deformability index of observation group after treatment were all less than those of control group (P<0.05; PAdT, PAgT, CD62p, CD40L and P-selectin values of observation group after treatment were all lower than those of control group (P<0.05; LPER and LPFR values of observation group 1 week after treatment were higher than those of control group while LTPER and LTPFR values were lower than those of control group (P<0.05; serum GA, MCP-1, PAI-1, NT-proBNP, PAC-1, VCAM-1 and ICAM-1 values of observation group after treatment were all lower than those of control group (P<0.05. Conclusions: Small dose of tirofiban combined with PCI treatment for patients with acute coronary syndrome can effectively enhance therapeutic effect, inhibit platelet activity while protect heart function and optimize long-term treatment outcome.

    Background The association between cardiorespiratory fitness, physical activity and coronary artery calcium (CAC) is unclear, and whether higher levels of fitness attenuate CAC prevalence in subjects with metabolic syndrome is not fully elucidated. The present study aims to: a) investigate the independent association of fitness on the prevalence of CAC, after adjustment for moderate-to-vigorous physical activity and sedentary time, and b) study the possible attenuation of increased CAC by higher fitness, in participants with metabolic syndrome. Design Cross-sectional. Methods In total 678 participants (52% women), 50-65 years old, from the SCAPIS pilot study were included. Fitness (VO 2 max) was estimated by submaximal cycle ergometer test and moderate-to-vigorous physical activity and sedentary time were assessed using hip-worn accelerometers. CAC score (CACS) was quantified using the Agatston score. Results The odds of having a significant CACS (≥100) was half in participants with moderate/high fitness compared with their low fitness counterparts. Further consideration of moderate-to-vigorous physical activity, sedentary time and number of components of the metabolic syndrome did only slightly alter the effect size. Those with metabolic syndrome had 47% higher odds for significant CAC compared with those without metabolic syndrome. However, moderate/high fitness seems to partially attenuate this risk, as further joint analysis indicated an increased odds for having significant CAC only in the unfit metabolic syndrome participants. Conclusions Being fit is associated with a reduced risk of having significant CAC in individuals with metabolic syndrome. While still very much underutilized, fitness should be taken into consideration in everyday clinical risk prediction in addition to the traditional risk factors of the metabolic syndrome.

    Clinical practice guidelines recommend admitting patients with stable non-ST-segment elevation acute coronary syndrome (NSTE ACS) to telemetry units, yet up to two-thirds of patients are admitted to higher-acuity critical care units (CCUs). The outcomes of patients with stable NSTE ACS initially admitted to a CCU vs a cardiology ward with telemetry have not been described. We used population-based data of 7,869 patients hospitalized with NSTE ACS admitted to hospitals in Alberta, Canada, between April 1, 2007, and March 31, 2013. We compared outcomes among patients initially admitted to a CCU (n=5,141) with those admitted to cardiology telemetry wards (n=2,728). Patients admitted to cardiology telemetry wards were older (median 69 vs 65years, PST-segment myocardial infarction or unstable angina. There were no differences in clinical outcomes observed between patients with NSTE ACS initially admitted to a ward or a CCU. These findings suggest that stable NSTE ACS may be managed appropriately on telemetry wards and presents an opportunity to reduce hospital costs and critical care capacity strain.

    Nonadherence to medication may lead to poor medical outcomes. To describe medication-taking behavior of patients with a history of acute coronary syndromes (ACS) for 4 classes of drugs and determine the relationship between self-reported adherence and patient characteristics. Consenting patients with the diagnosis of ACS were interviewed by telephone approximately 10 months after discharge. The survey elicited data characterizing the patient, current medication regimens, beliefs about drug therapy, reasons for discontinuing medications, and adherence. The survey included the Beliefs About Medicine Questionnaire providing 4 scales: Specific Necessity, Specific Concerns, General Harm, and General Overuse, and the Medication Adherence Scale (MAS). Multivariate regression was used to determine the independent variables with the strongest association to the MAS. A p value or =1 other person, and 42% indicating excellent or very good health. The percentage of patients continuing on medication at the time of the survey category ranged from 87.4% (aspirin) to 66.0% (angiotensin-converting enzyme inhibitors). Reasons for stopping medication included physician discontinuation or adverse effects. Of patients still on drug therapy, the mean MAS was 1.3 +/- 0.4, with 53.8% indicating nonadherence (score >1). The final regression model showed R(2) = 0.132 and included heart-related health status and Specific Necessity as significant predictor variables. After ACS, not all patients continue their drugs or take them exactly as prescribed. Determining beliefs about illness and medication may be helpful in developing interventions aimed at improving adherence.

    Hyperglycaemia has been associated with increased platelet reactivity and impaired prognosis in patients with acute coronary syndrome (ACS). Whether platelet reactivity can be reduced by lowering glucose in this setting is unknown. The aim of this study was to assess the functional impact of intensive glucose control with insulin on platelet reactivity in patients admitted with ACS and hyperglycaemia. This is a prospective, randomised trial evaluating the effects of either intensive glucose control (target glucose 80-120 mg/dl) or conventional control (target glucose 180 mg/dl or less) with insulin on platelet reactivity in patients with ACS and hyperglycaemia. The primary endpoint was platelet aggregation following stimuli with 20 μM ADP at 24 h and at hospital discharge. Aggregation following collagen, epinephrine and thrombin receptor-activated peptide, as well as P2Y₁₂ reactivity index and surface expression of glycoprotein IIb/IIIa and P-selectin were also measured. Of the 115 patients who underwent random assignment, 59 were assigned to intensive and 56 to conventional glucose control. Baseline platelet functions and inhospital management were similar in both groups. Maximal aggregation after ADP stimulation at hospital discharge was lower in the intensive group (47.9 ± 13.2% vs 59.1 ± 17.3%; p=0.002), whereas no differences were found at 24 h. Similarly all other parameters of platelet reactivity measured at hospital discharge were significantly reduced in the intensive glucose control group. In this randomised trial, early intensive glucose control with insulin in patients with ACS presenting with hyperglycaemia was found to decrease platelet reactivity.

    Full Text Available Abstract Introduction: A recently published study raised doubts about the need for percutaneous treatment of nonculprit lesions in patients with acute coronary syndromes (ACS. Methods: Retrospective, unicentric, observational study. Objective: To analyze the long-term outcomes in patients undergoing treatment of the culprit artery, comparing those who remained with significant residual lesions in nonculprit arteries (group I versus those without residual lesions in other coronary artery beds (group II. The study included 580 patients (284 in group I and 296 in group II between May 2010 and May 2013. We obtained demographic and clinical data, as well as information regarding the coronary treatment administered to the patients. In the statistical analysis, the primary outcome included combined events (reinfarction/angina, death, heart failure, and need for reintervention. The comparison between groups was performed using the chi-square test and ANOVA. The long-term analysis was conducted with the Kaplan-Meier method, with a mean follow-up of 9.86 months. Results: The mean ages were 63 years in group I and 62 years in group II. On long-term follow-up, there was no significant difference in combined events in groups I and II (31.9% versus 35.6%, respectively, p = 0.76. Conclusion: The strategy of treating the culprit artery alone seems safe. In this study, no long-term differences in combined endpoints were observed between patients who remained with significant lesions compared with those without other obstructions.

    Objective: Metabolic syndrome is a combination of medical disorders that consist of a collection of independent factors at risk of developing coronary artery disease. The purpose of this study was to evaluate the value of 99 Tc m -methoxyisobutylisonitrile (MIBI) myocardial perfusion imaging for the diagnosis of coronary artery disease in patients with metabolic syndrome. Methods: A total of 251 patients [mean age (59 ± 10) years, 179 men, 72 women] were included in this study. All patients underwent exercise and rest 99 Tc m -MIBI myocardial perfusion imaging and coronary angiography. Results: Of the 163 patients with significant coronary artery stenosis, 116 showed abnormal 99 Tc m -MIBI myocardial perfusion imaging; and among the 88 patients with normal coronary angiography, 82 showed normal myocardial perfusion imaging. The sensitivity, specificity and accuracy of 99 Tc m -MIBI myocardial perfusion imaging for coronary artery disease detection were 71% (116/163), 93% (82/88) and 79% (198/251), respectively. The positive and negative predictive values were 95% (116/122) and 64% (82/129), respectively. Conclusion: 99 Tc m -MIBI myocardial perfusion imaging has important clinical value for detecting coronary artery disease in patients with metabolic syndrome. (authors)

    Transluminal coronary angioplasty (TCA) was introduced in 1977 for dilatation of coronary stenoses. From October 1977 to December 1984 1087 procedures have been performed in Frankfurt. The mean success rate was 77% with an increase from 58% to 84% since 1977. Recurrences were seen within the first year in 15% of the patients, which could be treated successfully in a high percentage with a second TCA. Emergency bypass operations were necessary in 5.2%. Four patients (fatality rate 0.37%) died as the consequence of the intervention. Within few years TCA has become an established procedure for myocardial revascularisation, with a high success rate. Major progress has been possible in the last few years due to technical developments, which are still going on. They may lead to further improvement of the results and enlargement of the indication for TCA. (orig.) [de

    Diabetes mellitus (DM) and metabolic syndrome are important targets for secondary prevention in cardiovascular disease. However, the prevalence in patients undergoing elective percutaneous coronary intervention is not well defined. We aimed to analyse the prevalence and characteristics of patients undergoing percutaneous coronary intervention with previously unrecognized prediabetes, diabetes and metabolic syndrome. Data were collected from 740 patients undergoing elective percutaneous coronary intervention between November 2010 and March 2013 at a tertiary referral center. Prevalence of DM and prediabetes was evaluated using Haemoglobin A1c (A1c ≥ 6.5% for DM, A1c 5.7-6.4% for prediabetes). A modified definition was used for metabolic syndrome [three or more of the following criteria: body mass index ≥30 kg/m2; triglycerides ≥ 150 mg/dL; high density lipoprotein prediabetes at time of percutaneous coronary intervention. Overall, 54.9% met criteria for metabolic syndrome (69.2% of patients with DM and 45.8% of patients without DM). Among patients undergoing elective percutaneous coronary intervention, a substantial number were identified with a new DM, prediabetes, and/or metabolic syndrome. Routine screening for an abnormal glucometabolic state at the time of revascularization may be useful for identifying patients who may benefit from additional targeting of modifiable risk factors.

    Full Text Available AbstractObjectives: Regardless of diabetes status, hyperglycemia on arrival for patients presenting with acute coronary syndrome, has been associated with adverse outcomes including death. The aim of this study is to look at the frequency and prognostic significance of acute phase hyperglycemia among patients attending the coronary care unit with acute coronary syndrome over the in-hospital admission days.Methods: The study included 287 consecutive patients in the Al- Faiha Hospital in Basrah (Southern Iraq during a one year period from December 2007 to November 2008. Patients were divided into two groups with respect to admission plasma glucose level regardless of their diabetes status (those with admission plasma glucose of <140 mg/dl (7.8 mmol/L and those equal to or more than that. Acute phase hyperglycemia was defined as a non-fasting glucose level equal to or above 140 mg/dl (7.8 mmol/L regardless of past history of diabetes.Results: Sixty one point seven percent (177 of patients were admitted with plasma glucose of ≥140 mg/dl (7.8 mmol/L. There were no differences were found between both groups regarding the mean age, qualification, and smoking status, but males were predominant in both groups. A family history of diabetes, and hypertension, were more frequent in patients with plasma glucose of ≥140 mg/dl (7.8 mmol/L. There were no differences between the two groups regarding past history of ischemic heart disease, stroke, lipid profile, troponin-I levels or type of acute coronary syndrome. Again heart failure was more common in the admission acute phase hyperglycemia group, but there was no difference regarding arrhythmia, stroke, or death. Using logistic regression with heart failure as the dependent variable we found that only the admission acute phase hyperglycemia (OR=2.1344, 95�0CI=1.0282-4.4307; p=0.0419 was independently associated with heart failure.

    The optimal management approach for patients with non-ST-segment elevation acute coronary syndromes continues to be an issue of debate. An ischemia-guided strategy appears to be effective as an alternative to either a very conservative "wait-and-see" approach or a very aggressive routine revascularization approach. The need for another approach is supported by the lack of conclusive evidence-based results favoring an early routine invasive treatment strategy. In the Thrombolysis in Myocardial Infarction (TIMI) IIIB trial, there were no differences in the incidence of death or myocardial infarction (MI) between patients treated with an early invasive approach and those treated with a conservative approach to treatment. Significantly worse outcomes were shown in patients assigned to an early invasive strategy in the Veterans Affairs Non-Q-Wave Infarction Strategies in Hospital (VANQWISH) trial at 1-year follow-up (111 clinical events in the invasive group vs 85 in the conservative group; p = 0.05). Registry information, including that from the Organization to Assess Strategies for Ischemic Syndromes (OASIS), which included approximately 8,000 patients with unstable angina or suspected MI, has even suggested an excess hazard with a routine invasive approach. Patients with non-ST-segment elevation MI observed in the Global Use of Strategies to Open Occluded Coronary Arteries in Acute Coronary Syndromes (GUSTO)-IIB and Platelet IIb/IIIa in Unstable Angina: Receptor Suppression Using Integrilin Therapy (PURSUIT) trials also fared better with an ischemia-guided strategy. Even the recent FRagmin and Fast Revascularization during InStability in Coronary artery disease (FRISC II) trial investigators had to be very selective relative to eliminating high-risk patients in the first week and treating with intense anti-ischemic therapy and 5-7 days of low-molecular-weight heparin therapy to show an advantage for assigned revascularization.

    Women with polycystic ovary syndrome are characterized by obesity, menstruation irregularity, hirsutism and infertility, and prevalent with cardiometabolic comorbidities, but population-based studies on the risk of developing coronary artery disease are limited. From claims data of the Taiwan National Health Insurance, we identified 8048 women with polycystic ovary syndrome aged 15-49 years newly diagnosed in 1998-2013, and 32192 women without the syndrome and CAD as controls, frequency matched by age and diagnosis date. By the end of 2013, after a mean follow-up period of 5.9 years, the overall incidence of coronary artery disease was 63% higher in women with polycystic ovary syndrome than in controls (2.25 vs. 1.38 per 1000 person-years). The adjusted hazard ratio [aHR] of coronary artery disease was 1.44 (95% confidence interval (CI) = 1.14-1.81) for women with polycystic ovary syndrome, compared with controls. Hazards of coronary artery disease were significant during follow-up periods of 3-4 years (aHR = 1.52, 95% CI = 1.00-2.30) and of 5-9 years (aHR = 1.58, 95% CI = 1.07-2.32). The incidence of coronary artery disease increased further in those with cardiometabolic comorbidities. Among women with polycystic ovary syndrome, those with comorbid diabetes had an incidence of 35.2 per 1000 person-years, 20-fold greater than those without cardiometabolic comorbidities. In conclusion, women with polycystic ovary syndrome are at an elevated risk of coronary artery disease. Preventive interventions should be provided to them, particularly for those with the comorbidity of metabolism symptom.

    Coronary artery trees (CATs) are often extracted to aid the fully automatic analysis of coronary artery disease on coronary computed tomography angiography (CCTA) images. Automatically extracted CATs often miss some arteries or include wrong extractions which require manual corrections before performing successive steps. For analyzing a large number of datasets, a manual quality check of the extraction results is time-consuming. This paper presents a method to automatically calculate quality scores for extracted CATs in terms of clinical significance of the extracted arteries and the completeness of the extracted CAT. Both right dominant (RD) and left dominant (LD) anatomical statistical models are generated and exploited in developing the quality score. To automatically determine which model should be used, a dominance type detection method is also designed. Experiments are performed on the automatically extracted and manually refined CATs from 42 datasets to evaluate the proposed quality score. In 39 (92.9%) cases, the proposed method is able to measure the quality of the manually refined CATs with higher scores than the automatically extracted CATs. In a 100-point scale system, the average scores for automatically and manually refined CATs are 82.0 (+/-15.8) and 88.9 (+/-5.4) respectively. The proposed quality score will assist the automatic processing of the CAT extractions for large cohorts which contain both RD and LD cases. To the best of our knowledge, this is the first time that a general quality score for an extracted CAT is presented.

    A 70-year old man presented with retrosternal chest pain. His electrocardiogram showed nonspecific T wave changes. Cardiac-specific troponin I (cTnI) was elevated. His condition was managed as acute coronary syndrome, following which he had two minor episodes of hemoptysis. A CT pulmonary angiogram showed no evidence of pulmonary embolism, but a large mass lesion was seen in the mediastinum. Echocardiography and cardiac MRI demonstrated a large solid mass, arising from the right ventricular outflow tract and causing compression of the main pulmonary artery (MPA). The differential diagnosis included pericardial and myocardial tumors and clotted aneurysm of the MPA. At surgery, a clotted aneurysmal sac was identified originating from the MPA and the defect was healed. Aneurysms of the MPA are rare. They most commonly present with dyspnea and chest pain. Compression of surrounding structures produces protean manifestations. A high index of suspicion coupled with imaging modalities establishes the diagnosis. Blunt trauma to the chest, at the time of an accident 4 years previously, may explain this aneurysm. The patient's presentation with chest pain was probably due to compression and/or stretching of surrounding structures. Coronary artery compression simulating acute coronary syndrome has been documented in the literature. The rise in cTnI may have been due to right ventricular strain, as a result of right ventricular outflow obstruction by the aneurysm. This has not been reported previously in the literature. The saccular morphology and narrow neck of the aneurysm predisposed to stagnation leading to clotting of the lumen and healing of the tear, which caused the diagnostic difficulty

    Objective Absence of significant epicardial coronary artery disease (CAD) in patients with acute onset of chest pain and elevation of myocardial necrosis markers is occasionally observed. The aim of this study was to analyse the clinical characteristics and outcome of such patients with advanced age. Methods We retrospectively analysed 4,311 patients with acute onset of chest pain plus necrosis marker elevation. Two hundred and seventy two patients without CAD on angiogram (6.3%) were identified. Out of them, 50 (1.2%) patients ≥ 75 years (Group I) were compared with (1) 222 acute coronary syndrome (ACS) patients without CAD on angiogram < 75 years (Group II), and (2) 610 consecutive patients ≥ 75 years with Non-ST-elevation Myocardial Infarction (NSTEMI) undergoing percutaneous coronary intervention (Group III). Results Group I compared to Group III patients made up for more females (64.0% vs. 49.2%; P < 0.0001), and had more severe anginal symptoms on presentation [Canadian Cardiovascular Society (CCS) class I/II, 26.0% vs. 49.8%; P = 0.02]. Group I patients also had lower troponin levels (0.62 ± 0.8 ng/mL vs. 27 ± 74 ng/mL; P < 0.02), lower leukocyte count (9.4 ± 3.13 × 109 vs. 12 ± 5.1 × 109; P = 0.001) and better preserved left ventricular function (56.7% ± 14.3% vs. 45% ± 11%; P < 0.0001). Event-free survival (cardiac death, myocardial infarction, recurrent angina, and re-hospitalisation) was more frequent in Group I and II patients compared to Group III patients (64.9%, 66.7%, and 41.6%, respectively; P < 0.0001). Conclusions ACS in patients ≥ 75 years without CAD is very infrequent, associated with a (1) similar outcome compared to ACS patients < 75 years without CAD, and (2) significant better outcome compared to NSTEMI patients ≥ 75 years.

    Patients with acute coronary syndrome (ACS) frequently have vulnerable plaques in the remote coronary arteries, suggesting that ACS is part of the pan-coronary process. In the present study the computed tomography (CT) plaque density in non-culprit atherosclerotic coronary artery lesions was evaluated by multi-slice computed tomography (MSCT) in patients with ACS and non-ACS. MSCT was performed in 21 patients with ACS and 53 patients with non-ACS: 16 of the 21 ACS patients (76%) and 30 of the non-ACS 53 patients (57%) had non-calcified plaques in the non-culprit coronary arteries (p=0.18). CT-low-density plaques (CT density <68 Hounsfield units (HU)) were more frequent in the ACS group (13/16 patients, 81%) than in the non-ACS group (13/30 patients, 43%, p=0.03). In addition, the CT density of the non-culprit lesion was significantly lower in patients with ACS than in those with non-ACS (44.1±22.9 and 77.3±33.7 HU, respectively). Patients with ACS more frequently had CT-low-density plaques in the non-culprit, remote arteries than those with non-ACS, which suggests that ACS treatment should focus not only on stabilizing the culprit lesion but also on systemic stabilization of non-culprit lesions.

    Full Text Available Abstract Background Type 2 diabetes and the metabolic syndrome are associated with impaired diastolic function and increased heart failure risk. Animal models and autopsy studies of diabetic patients implicate myocardial fibrosis, cardiomyocyte hypertrophy, altered myocardial microvascular structure and advanced glycation end-products (AGEs in the pathogenesis of diabetic cardiomyopathy. We investigated whether type 2 diabetes and the metabolic syndrome are associated with altered myocardial structure, microvasculature, and expression of AGEs and receptor for AGEs (RAGE in men with coronary artery disease. Methods We performed histological analysis of left ventricular biopsies from 13 control, 10 diabetic and 23 metabolic syndrome men undergoing coronary artery bypass graft surgery who did not have heart failure or atrial fibrillation, had not received loop diuretic therapy, and did not have evidence of previous myocardial infarction. Results All three patient groups had similar extent of coronary artery disease and clinical characteristics, apart from differences in metabolic parameters. Diabetic and metabolic syndrome patients had higher pulmonary capillary wedge pressure than controls, and diabetic patients had reduced mitral diastolic peak velocity of the septal mitral annulus (E', consistent with impaired diastolic function. Neither diabetic nor metabolic syndrome patients had increased myocardial interstitial fibrosis (picrosirius red, or increased immunostaining for collagen I and III, the AGE Nε-(carboxymethyllysine, or RAGE. Cardiomyocyte width, capillary length density, diffusion radius, and arteriolar dimensions did not differ between the three patient groups, whereas diabetic and metabolic syndrome patients had reduced perivascular fibrosis. Conclusions Impaired diastolic function of type 2 diabetic and metabolic syndrome patients was not dependent on increased myocardial fibrosis, cardiomyocyte hypertrophy, alteration of the

    The objective was to determine the association of four clinical risk scores and coronary plaque burden as detected by computed tomography (CT) with the outcome of acute coronary syndrome (ACS) in patients with acute chest pain. The hypothesis was that the combination of risk scores and plaque burden improved the discriminatory capacity for the diagnosis of ACS. The study was a subanalysis of the Rule Out Myocardial Infarction Using Computer-Assisted Tomography (ROMICAT) trial-a prospective observational cohort study. The authors enrolled patients presenting to the emergency department (ED) with a chief complaint of acute chest pain, inconclusive initial evaluation (negative biomarkers, nondiagnostic electrocardiogram [ECG]), and no history of coronary artery disease (CAD). Patients underwent contrast-enhanced 64-multidetector-row cardiac CT and received standard clinical care (serial ECG, cardiac biomarkers, and subsequent diagnostic testing, such as exercise treadmill testing, nuclear stress perfusion imaging, and/or invasive coronary angiography), as deemed clinically appropriate. The clinical providers were blinded to CT results. The chest pain score was calculated and the results were dichotomized to ≥10 (high-risk) and modeling was performed to examine the association of risk scores and coronary plaque burden to the outcome of ACS. Unadjusted models were individually fitted for the coronary plaque burden and for Goldman, Sanchis, TIMI, and chest pain scores. In adjusted analyses, the authors tested whether the association between risk scores and ACS persisted after controlling for the coronary plaque burden. The prognostic discriminatory capacity of the risk scores and plaque burden for ACS was assessed using c-statistics. The differences in area under the receiver-operating characteristic curve (AUC) and c-statistics were tested by performing the -2 log likelihood ratio test of nested models. A p value capacity for the diagnosis of ACS. Plaque burden was

    The prognostic impact of β-blockers (BB) in acute coronary syndrome (ACS) patients without heart failure (HF) or left ventricular dysfunction is controversial, especially in the postreperfusion era. We sought to determine whether a BB therapy before admission for ACS has a favorable in-hospital outcome in patients without HF, and whether they also reduce 12-month mortality if still prescribed on discharge. The GULF-RACE 2 (Gulf Registry of Acute Coronary Events-2) is a prospective multicenter study of ACS in 6 Middle Eastern countries. We studied in-hospital cardiovascular events in patients hospitalized for ACS without HF in relation to BB on admission, and 1-year mortality in relation to BB on discharge. Among the 7903 participants, 7407 did not have HF, of whom 5937 (80.15%) patients were on BB. Patients on BB tended to be older and have more comorbidities. However, they had a lower risk of in-hospital mortality, mitral regurgitation, HF, cardiogenic shock, and ventricular tachycardia/ventricular fibrillation. Furthermore, 4208 patients were discharged alive and had an ejection fraction ≥40%. Among those, 84.1% had a BB prescription. At 12 months, they also had a reduced risk of mortality as compared with the non-BB group. Even after correcting for confounding factors in 2 different models, in-hospital and 12-month mortality risk was still lower in the BB group. In this cohort of ACS, BB therapy before admission for ACS is associated with decreased in-hospital mortality and major cardiovascular events, and 1-year mortality in patients without HF or left ventricular dysfunction if still prescribed on discharge. © 2017 The Authors.

    Full Text Available Normal 0 false false false EN-US X-NONE X-NONE Depression and anxiety are two conditions that common happened in patient with acute coronary syndrome which can cause negative cardiovascular outcomes. Although the prevalencies of these two conditions are slightly high, most of them had not been treated well. The mechanisms that underly the association between depression and anxiety with the negative cardiovascular outcome are possibly correlates with their effect on inflammatory process, cathecolamine release, heart rate variability, endothelial function and also their effect on health promoting behavior. Fortunately, the standard therapies that available for these conditions are safe, effective, and can be tolerated well in most patients. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

    The aim of the present study was to determine the early and long-term outcomes of coronary artery bypass grafting in patients with acute coronary syndrome and stable angina pectoris. From September 2004 to September 2011, 382 patients with acute coronary syndrome (unstable angina pectoris and non-ST-segment elevation myocardial infarction) and 851 patients with stable angina pectoris underwent first-time isolated coronary artery bypass grafting at our institute. The early and long-term outcomes were compared between the 2 groups. Patients with acute coronary syndrome were older, were more likely to be women, had a smaller body surface area, and were more likely to have left main coronary artery disease. In both groups, bilateral internal thoracic artery grafts were used in approximately 89% of the patients, and off-pump techniques in approximately 97% of the patients. The acute coronary syndrome group had a greater operative death rate (2.6% vs 0.1%) and a greater incidence of low output syndrome (3.1% vs 1.2%) and hemodialysis requirement (2.9% vs 1.1%). Multivariate regression analysis demonstrated that age, acute coronary syndrome, lower ejection fraction, and higher creatinine level before surgery were independent predictors of operative death. However, among the hospital survivors, no differences were seen in freedom from all death (85.4% ± 2.5% vs 87.7% ± 2.0%), cardiac death (97.4% ± 0.9% vs 96.5% ± 0.9%), or major adverse cardiac and cerebrovascular events (78.0% ± 2.9% vs 78.1% ± 2.3%) at 7 years between the patients with acute coronary syndrome and stable angina pectoris. Although acute coronary syndrome is an independent predictor of early mortality in patients undergoing coronary artery bypass grafting, the long-term outcomes after surgery were similar between patients with acute coronary syndrome and stable angina pectoris who survived the early postoperative period.

    To assess prevalence, characteristics and management of acute coronary syndromes in sub-Saharan Africa population. Prospective survey from January, 2010 to December, 2013, carried out among patients aged 18 years old, admitted to intensive care unit of Abidjan Heart Institute for acute coronary syndrome (ACS). Four hundred and twenty-five (425) patients were enrolled in this study. Prevalence of ACS was 13.5%. Mean age was 55.4±11 years. Clinical presentation was predominantly ST-segment elevation myocardial infarction (STEMI) in 71.5% of subjects, non-ST-segment elevation acute coronary syndrome (NSTE-ACS) accounted for 28.5%. Two hundred and eighty patients (65.9%) were transferred by unsafe transportation. Among the 89 patients admitted within 12hours of the onset of symptoms, primary percutaneous coronary intervention was performed in 20 patients (22.5%), or 6.6% of STEMI as a whole. Twenty-five patients (8.2%) received fibrinolytic therapy with alteplase. In-hospital death rate was 10%. The prevalence of acute coronary syndromes is increasing in sub-Saharan Africa. Excessive delays of admission and limited technical facilities are the major difficulties of their management in our regions. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Patients with chest pain, elevated troponin, and unobstructed coronary disease present a clinical dilemma. The purpose of this study was to investigate the incremental diagnostic value of cardiovascular magnetic resonance (CMR) in a cohort of patients with suspected acute coronary syndrome (ACS) and unobstructed coronary arteries. Data files of patients meeting the inclusion criteria in two cardiology centres were searched and analysed. The inclusion criteria included: 1) thoracic pain suspected with ACS; 2) a significant increase in the high-sensitive Troponin T value; 3) ECG changes; 4) coronary arteries without any significant stenosis; 5) a CMR examination included in the diagnostic process; 6) an uncertain diagnosis before the CMR exam; and 7) the absence of known CMR and contrast media contraindications. Special attention was paid to the benefits of CMR in determining the final diagnosis. In total, 136 patients who underwent coronary angiography for chest pain were analysed. The most frequent underlying causes were myocarditis (38%) and perimyocarditis (18%), followed by angiographically unrecognised acute myocardial infarction (18%) and Takotsubo cardiomyopathy (15%). The final diagnosis remained unclear in 6% of the patients. The contribution of CMR in determining the final diagnosis determination was crucial in 57% of the patients. In another 35% of the patients, CMR confirmed the suspicion and, only 8% of the CMR examinations did not help at all and had no influence on diagnosis or treatment. CMR provided a powerful incremental diagnostic value in the cohort of patients with suspected ACS and unobstructed coronary arteries. CMR is highly recommended to be incorporated as an inalienable part of the diagnostic algorithms in these patients.

    Patients with acute coronary syndrome complicated with high degree atrioventricular block still have a high mortality. A low percentage of these patients need a permanent pacemaker (PPM) but mortality and associated factors with the PPM implant in acute coronary syndrome patients are not known. We assess whether PPM implant is an independent variable in the mortality of acute coronary syndrome patients. Also, we explored the variables that remain independently associated with PPM implantation. This was an observational study on the Spanish ARIAM register. The inclusion period was from January 2001 to December 2011. This registry included all Andalusian acute coronary syndrome patients. Follow-up for global mortality was until November 2013. We selected 27,608 cases. In 62 patients a PPM was implanted (0.024%). The mean age in PPM patients was 70.71±11.214 years versus 64.46±12.985 years in patients with no PPM. PPM implant was associated independently with age (odds ratio (OR) 1.031, 95% confidence interval (CI) 1.007-1.055), with left ventricular branch block (OR 6.622, 95% CI 2.439-18.181), with any arrhythmia at intensive care unit admission (OR 2.754, 95% CI 1.506-5.025) and with heart failure (OR 3.344, 95% CI 1.78-8.333). PPM implant was independently associated with mortality (OR 11.436, 95% CI 1.576-83.009). In propensity score analysis PPM implant was still associated with mortality (OR 5.79, 95% CI 3.27-25.63). PPM implant is associated with mortality in the acute coronary syndrome population in the ARIAM registry. Advanced age, heart failure, arrhythmias and left ventricular branch block at intensive care unit admission were found associated factors with PPM implant in acute coronary syndrome patient.

    Chlamydia pneumoniae is one of the infectious factors the role of which is considered in the process of atherosclerosis and its complications. Of the study was to assess the incidence of Ch. pneumoniae infection in the patients with acute coronary events. The study was carried out in 36 patients, mean age 61.2 +/- 13.4 years, 27 men and 9 women hospitalised in our Department with the diagnosis of previous or recent acute myocardial infarction. The control group consisted of 19 subjects, aged 61.1 +/- 14.3 years, 10 men and 9 women hospitalised due to other reasons. In all studied patients during the first 24 hours venous blood was taken for the assessment of fibrinogen and C-reactive protein (CRP) concentrations and titres of IgA and IgG anti-Ch. pneumoniae antibodies, and pharyngeal swabs were done for Ch. pneumoniae assessment. Positive swab tests were found in 19% of the patients, positive IgG titres in 80% and IgA in 64% of the patients. In the control group the corresponding values were 11, 79, 42%, respectively. In the patients with positive IgG titres, negative IgA titre result was observed in 21% and in the control group in 53% (p < 0.05). The CRP level was significantly higher in the studied patients than in the control group (24.2 vs 4.2 mg/l; p < 0.05). 1. The high percentage of positive serologic tests and rare positive results of pharyngeal swabs indicate a frequent contact with Ch. pneumoniae in human population. 2. Ch. pneumoniae infection exerts no significant influence on the unspecific markers of inflammation. 3. The higher frequency of seroconversion-positive IgG and negative IgA titres--in the control group indicates the role of prolonged or acute Ch. pneumoniae infection in the development or progression of coronary atherosclerosis and its complications.

    Full Text Available Abstract Background Shorter time to treatment is associated with lower mortality in acute coronary syndromes (ACS. A previous (1994 survey showed substantial delays for acute myocardial infarction (AMI in Ireland. The present study compared current practice with 1994 and surveyed acute coronary syndromes as a more complete contemporary evaluation of critical cardiac care than assessing AMI alone. Methods Following ethics committee approval, all centres (N = 39 admitting acute cardiac patients to intensive/coronary care unit provided information on 1365 episodes. A cross-sectional survey design was employed. Results Since 1994, median hospital arrival to thrombolysis time was reduced by 41% (76 to 45 minutes. Thrombolysis was delivered more often in the emergency department in 2003 (48% vs 2%. Thrombolysis when delivered in the emergency department was achieved faster than thrombolysis delivered in intensive/coronary care (35 mins v 60 mins; z = 5.62, p Conclusions Substantial improvements in time to thrombolysis have occurred since 1994, probably relating to treatment provision in emergency departments. Patient delay pre-hospital is still the principal impediment to effective treatment of ACS. A recent change of definition of AMI may have precluded an exact comparison between 1994 and 2003 data.

    Patients with coronary diseases admitted to special care unit often suffer from sleep disorders, which may cause physiological changes and adversely affect patient's health. The relationship between sleep disorders and obesity is an important factor in studies on sleep disorders and other chronic diseases in all groups, including cardiovascular diseases. Understanding this relationship may increase the chance of progress in effective medical interventions in sleep disorders and obesity. This study was designed to evaluate the association between short sleep and Body Mass Index (BMI), hypertension among acute coronary syndrome patients. In this descriptive analytical study, 221 coronary patients admitted to coronary care unit and general wards were investigated. Data were collected through a researcher-made questionnaire whose validity and reliability had been confirmed. Data were analyzed with SPSS-16 software. A total of 221 patients with acute coronary diseases (including myocardial infarction and angina pectoris) with a mean age of 61.27 years were studied, of whom 61.5% were male and 38.5% were female. A significant association was observed between short sleep and higher BMI (P=0.000). About half the patients (49.3%) had a history of hypertension, and sleep disorders were also significantly related to hypertension (P=0.006). In this study, sleep disorders were patients' main complaint. Researchers found that patients with less than 5 hours or more than 9 hours sleep at night were more likely to have hypertension compared to patients that slept 7-8 hours. Lack of sleep affects metabolism, and daily energy expenditure reduces with increased immobility. In this study, a significant relationship was observed between BMI and sleep duration among hospitalized patients in coronary care unit (P=0.000), and sleep disorders increased with higher BMI. Short of sleep increases sympathetic tonus, cortisol level, and activation of inflammatory pathways, impairing glucose

    To determine levels of C-reactive protein (CRP) and its association with coronary markers, lipid profile and markers of coagulation in patients of acute coronary syndrome (ACS). The study was conducted at Shifa college of Medicine and Shifa international hospital for a period of one year (November 2005-December 2006). Patients and Methods: Sixty nine age matched controls and 133 consecutive patients of ACS were included in the study. CRP were measured by immunoturbidometric method, MB fraction of creatine kinase (CK-MB) and Troponin-1 by micro-particle enzyme immunoassay, lipid levels by Colorimetric Enzymatic methods, platelets by celldyn and coagulation markers were measured by CA-50 Sysmax. At admission mean CRP levels, cardiac biomarkers, lipid profile and coagulation markers were significantly increased in patients of ACS versus controls. Within the patients of ACS the mean levels of CRP, CK-MB, Trop I, prothrombin time (PT) and activated partial thromboplastin time (Am) were significantly raised in patients with ST - elevation myocardial infarction (STEMI) and non STEMI (NSTEMI) versus patients of unstable angina (VA). Association between CRP levels and coronary markers, coagulation markers and lipid profile was found to be non significant. The CRP levels were increased in patients with ACS as compared to controls. The CRP levels were insignificantly correlated with coronary markers (CK-MB, Trop I), coagulation markers (platelet count, PT, Am), and lipid profile (cholesterol, triglyceride, HDL and LDL cholesterol) in patients with ACS.

    Acute kidney injury (AKI) complicating percutaneous coronary intervention (PCI) is associated with adverse clinical outcomes. To date, no studies have evaluated the association of blood transfusion with AKI in patients undergoing PCI. We used a retrospective cohort study of all patients with acute coronary syndrome undergoing PCI from CathPCI Registry (n=1 756 864). The primary outcome was AKI defined as the rise in serum creatinine post procedure ≥0.5 mg/dL or ≥25% above baseline values. AKI developed in 9.0% of study sample. Patients with AKI were older, more often women, and had high prevalence of comorbidities, including diabetes mellitus, hypertension, and advanced stages of chronic kidney disease at baseline. Blood transfusion was utilized in 2.2% of patients. In the overall sample, AKI developed in 35.1% of patients who received transfusion versus 8.4% of patients without transfusion (adjusted odds ratio, 4.87 [4.71-5.04]). In the subgroup of patients who sustained bleeding event and received transfusion, the rate of AKI was significantly increased across all preprocedure hemoglobin levels versus no blood transfusion. Similar findings were seen in the subgroup of patients with no bleeding event. Blood transfusion is strongly associated with AKI in patients with acute coronary syndrome undergoing PCI. Further investigation is needed to determine whether a restrictive blood transfusion strategy might improve PCI outcomes by reducing the risk of AKI. © 2016 American Heart Association, Inc.

    Coronary artery disease (CAD) is the major cause of death nearly all over the world, and accurate and rapid diagnosis of CAD is of major medical and economic importance. The aim of this study was to evaluate the serum and saliva levels of cathepsin L in patients with acute coronary syndrome (ACS). In a cross-sectional study, 39 patients with ACS and 28 with controls were recruited to the study, and cathepsin L levels were measured in serum, resting saliva, and stimulated saliva obtained 12 and 24 h after the onset of ACS by ELISA method. Statistical analyses of Fisher's exact test, the Student's t-test or Kruskal-Wallis test were performed. Stimulated saliva cathepsin L levels in patients with ACS 12 hours but not 24 hours after admission showed significant decrease compared with that in control subjects. However, there were no significant differences in serum and unstimulated saliva cathepsin L levels between groups. Serum and saliva levels of cathepsin L remain unchanged in patients with ACS and hence may not be a promising factor in CAD risk assessment. It seems that serum and saliva cathepsin L may not be a good biomarker for CHD.

    To examine trends in the use of diagnostic coronary angiography according to distance from home to the nearest invasive heart centre following implementation of fast-track protocols and extensive pre-hospital triaging of acute coronary syndrome patients. We performed a register-based cohort study of all patients admitted to Danish hospitals with incident acute coronary syndrome in 2005-2011. Diagnostic coronary angiography within 60 days of admission was investigated according to distance tertiles (DTs) calculated as range from each patient's home to the nearest invasive heart centre (short DT: 65 km). Cox proportional hazards models were applied.Among the 52,409 patients included, diagnostic coronary angiography was increasingly used during 2005-2011 (short DT: 76% to 81%; medium DT: 74% to 81%; long DT: 69% to 78%; all p-values for trend coronary angiography, and 60-day mortality decreased in all DT. This nationwide study found significant increases in diagnostic coronary angiography use over time in incident acute coronary syndrome patients with a relatively larger increase in patients residing farthest from an invasive heart centre. Additionally, selected quality of care measures improved in the entire cohort, suggesting a benefit of national clinical protocols. © The European Society of Cardiology 2014.

    Most of acute coronary syndromes (ACS) were receiving intervention treatment a high overall rate of coronary angiography in the modern medical practice.Consequently, we conduct a review to determine the heart rate (HR) on the prognosis of ACS in the coronary intervention era. PubMed, EMBASE, MEDLINE, and the Cochrane Library was systematically searched up to May 2016 using the search terms "heart rate," "acute coronary syndrome," "acute myocardial infarction," "ST elevation myocardial infarction," "non-ST-segment elevation." The outcome of interest was all-cause mortality. All analyses were performed using Review Manager. Database searches retrieved 2324 citations. Eleven studies enrolling 156,374 patients were included. In-hospital mortality was significantly higher in the elevated HR group compared to the lower HR group (pooled RR 2.04, 95%CI 1.80-2.30, P coronary intervention era.

    Full Text Available The final most common pathway for the majority of coronary artery disease is occlusion of a coronary vessel. Under normal conditions, antithrombin III (AT III, protein C, and protein S as an active protein C cofactor, are natural anticoagulants (hemostatic control that balances procoagulant activity (thrombin antithrombin complex balance to prevent thrombosis. If the condition becomes unbalanced, natural anticoagulants and the procoagulants can lead to thrombosis. Thirty subjects with acute coronary syndrome (ACS were studied for the incidence of antithrombin III (AT III, protein C, and protein S deficiencies, and the result were compare to the control group. Among patients with ACS, the frequency of distribution of AT-III with activity < 75% were 23,3% (7 of 30, and only 6,7% ( 2 of 30 in control subject. No one of the 30 control subject have protein C activity deficient, in ACS with activity < 70% were 13,3% (4 of 30. Fifteen out of the 30 (50% control subjects had protein S activity deficiency, while protein S deficiency activity < 70% was found 73.3.% (22 out of 30. On linear regression, the deterministic coefficient of AT-III activity deficiency to the development ACS was 13,25 %, and the deterministic coefficient of protein C activity deficient to the development of ACS was 9,06 %. The cut-off point for AT-III without protein S deficiency expected to contribute to the development of vessel disease was 45%. On discriminant analysis, protein C activity deficiency posed a risk for ACS of 4,5 greater than non deficient subjects, and AT-III activity deficiency posed a risk for ACS of 3,5 times greater than non deficient subjects. On binary logistic regression, protein S activity acted only as a reinforcing factor of AT-III activity deficiency in the development of ACS. Protein C and AT III deficiency can trigger ACS, with determinant coefficients of 9,06% and 13,25% respectively. Low levels of protein C posed a greater risk of

    Objective: To investigate the relationship between plasma TNF-α, IL-1β and CRP levels in aged patients with coronary heart disease and to define the inflammation marker which might recognize and predict acute coronary syndrome. Methods: Radioimmunoassay was used to detect plasma levels of TNF-α, IL-1β and CRP. Results: Plasma levels of TNF-α and IL-β in patients with acute coronary syndrome (ACS) were significantly higher than those in controls (p<0.05; p<0.01) and stable coronary heart disease (SCHD) (p<0.05; p<0.01). Plasma CRP levels in patients with ACS (7.99 +- 11.9 ml/L) were also significantly higher than those in controls (0.99 +- 1.5 mg/L; p<0.01) and patients with SCHD (2.71 +- 5.45 mg/L; p<0.05). There was positive correlation between CRP level and TNF-α (r=0.0545; p<0.01) as well as IL-β (r=0.31, p<0.05). Conclusion: The abnormal expression of cytokines in aged patients with coronary heart disease was correlative to inflammation marker CRP, which suggested that the abnormal expression to the occurrence of acute coronary syndrome and might serve as a marker of unstable atherosclerosis plaque

    Purpose: To evaluate a new coronary MR angiography technique covering the whole coronary artery tree in one data set acquisition. Materials and methods: Six healthy volunteers and 15 patients with known CAD were examined with a navigator gated and corrected (NAV) free-breathing 3D steady-state free precession sequence covering the whole heart (WH-MRA) (TR=5.4, TE-2.7, SENSE factor=2, 160 slices, 0.75 mm reconstructed slice thickness, in-plane resolution =0.99 x 0.99 mm 2 , scan time 14 min [50% NAV efficiency]) and a vessel targeted 3D SSFP MRA sequence (t-MRA) (TR=5.6 ms, TE-2.8 ms, 20 slices of 1.5 mm reconstructed slice thickness, in-plane resolution =0.99 x 0.99 mm 2 , scan time=7 min [50% NAV efficiency]). Subjective image quality (4-point scale) and objective image quality parameters including vessel sharpness, vessel diameter and CNR were calculated for WH-MRA and t-MRA. In patients, the accuracy for detection of stenosis larger than 50% was compared to the accuracy of X-ray coronary angiography (XA), which was considered the standard. Results: WH-MRA demonstrated good vessel visibility in healthy subjects (100%) whereas vessel visibility in patients was limited (78% in an 8 segment evaluation). Vessel sharpness was inferior to that of t-MRA in patients (37 vs. 42%) but equal in healthy subjects (42%). Vessel diameter did not differ significantly between WH-MRA and t-MRA. CNR was significantly reduced for WH-MRA (CNR 7.4 vs. 11.5). The diagnostic accuracy for the detection of CAD was comparable for both MRA approaches (85.5 vs. 86.2%). Conclusion: WH-MRA allows good coronary artery visualization in healthy subjects and patients and provides a simplified scanning procedure and advantages in 3D post-processing. Regarding image parameters and the detection of CAD, the results are comparable to those acquired with t-MRA. The major disadvantage remains the high number of diagnostically insufficient images.

    A 61-year-old patient with Wolff-Parkinson-White's syndrome, and hypertension was admitted to the CCU, because of the first episode of substernal chest pain. ECG was deformed by Wolff-Parkinson-White's syndrome, type B, with accessory pathway located on the right side, without evolution. Serum enzymes remained low. Echocardiography showed akinesis of the posterior wall and hypokinesis of the lateral wall (the same contraction disorders were described in previous echocardiographical examination 5 years ago), it was observed that the first portion of myocardium to contract was the base of the right ventricle. To elucidate the etiology of the contraction disorders, scintigraphy of the heart, using thallium 201, was performed, showing normal perfusion of the myocardium. To illustrate the dependence of the contraction disorders and abnormal depolarization pattern of the heart, echocardiographical examination was repeated, confirming the previous results, then 100 mg of Ajmaline was given to the patient intravenously, and echocardiographical examination was continued. Administration of the drug caused antidromic atrioventricular re-entrant tachycardia during which the lateral wall of the heart had been contracting properly. This case shows contraction disorders of the heart caused by the abnormal depolarization pattern, resulting from the presence of accessory pathway. It also illustrates the diagnostic difficulties in patients with Wolff-Parkinson-White's syndrome and suspected myocardial infarction, at the same time showing that scintigraphy of the heart might be very helpful in such patients. This case confirms the usefulness of echocardiography for localization of the accessory pathway. (author)

    Full Text Available Patients with metabolic syndrome are at high-risk for development of atherosclerosis and cardiovascular events. The objective of this study was to examine the major determinants of coronary disease severity, including those coronary risk factors associated with metabolic syndrome, during the early period after an acute coronary episode. We tested the hypothesis that inflammatory markers, especially highly sensitive C-reactive protein (hsCRP, are related to coronary atherosclerosis, in addition to traditional coronary risk factors. Subjects of both genders aged 30 to 75 years (N = 116 were prospectively included if they had suffered a recent acute coronary syndrome (acute myocardial infarction or unstable angina pectoris requiring hospitalization and if they had metabolic syndrome diagnosed according to the National Cholesterol Education Program/Adult Treatment Panel III. Patients were submitted to a coronary angiography and the burden of atherosclerosis was estimated by the Gensini score. The severity of coronary disease was correlated (Spearman’s or Pearson’s coefficient with gender (r = 0.291, P = 0.008, age (r = 0.218, P = 0.048, hsCRP (r = 0.256, P = 0.020, ApoB/ApoA ratio (r = 0.233, P = 0.041, and carotid intima-media thickness (r = 0.236, P = 0.041. After multiple linear regression, only male gender (P = 0.046 and hsCRP (P = 0.012 remained independently associated with the Gensini score. In this high-risk population, male gender and high levels of hsCRP, two variables that can be easily obtained, were associated with more extensive coronary disease, identifying patients with the highest potential of developing new coronary events.

    Risk evaluation of patients hospitalized with acute coronary syndrome (ACS) may contribute to their short-term prognosis improvement. The aim of this work was to develop a prediction index (score) for the risk assessment of 30-day death of ACS patients, using clinical and biological measurements at hospital admission. A sample of 6 Greek hospitals was selected, and almost all consecutive 2172 ACS patients from October 2003 to September 2004 were enrolled. Sociodemographic, biochemical, clinical, and lifestyle characteristics were recorded. Using as components age, systolic blood pressure, white blood cell count, creatine kinase-MB, and creatinine levels at the time of admission and the time between the onset of symptoms and presentation at hospital, a risk score (Greek Acute Coronary Syndrome score; range, 6-36) was developed and tested against in-hospital and 30-day outcome of the patients. The Greek Acute Coronary Syndrome score showed strong discriminating ability for in-hospital mortality (area under the receiver operating characteristic curve, 0.812; 95% confidence interval, 0.750-0.874; P period.

    2010-01-01

    Objective: We tried to understand significance of increased triglyceride (TG) values in metabolic syndrome and coronary artery disease (CAD). Methodology: Check up cases with a TG value lower than 60 mg/dL were collected into the first, between 60 and 99 mg/dL into the second, between 100 and 149 mg/dL into the third, between 150 and 199 into the fourth, and 200 mg/dL and greater into the fifth groups. Results: Study included 478 cases. Values of the mean age, weight, body mass index, TG, and low density lipoprotein cholesterol (LDL-C) and prevalence of smoking, white coat hypertension (WCH), hypertension (HT), type 2 diabetes mellitus (DM), and CAD increased gradually and significantly nearly in all steps from the first towards the fifth groups. Conclusion: Metabolic syndrome may be a progression step between complete physical health and irreversible end points, such as obesity, type 2 DM, HT, CAD, and stroke. Hypertriglyceridemia and White Coat Hypertension (WCH) may be the most significant reversible parameters of the syndrome, and it is better to have the lowest TG value as much as possible. The most significant increase was seen after the value of 100 mg/dL. The overweight, smoking, hypertriglyceridemia, hyperbetalipoproteinemia, and WCH may only be one of hundreds of parameters of the syndrome. Therefore, it is advisable that underlying etiologies rather than reversible parameters of the syndrome should be targeted for treatment. For example, increased TG and LDL-C values, and prevalence of WCH by aging may be secondary to decreased physical and mental stresses in elderly. (author)

    Background: Myocardial perfusion imaging tests are used for the clinical assessment of patients hospitalized with non-ST segment elevation acute coronary syndromes (NSTACS) who have favorable in-hospital outcomes with medical therapy. However, the prognostic relevance of a .low ischemic risk. (LR) single photon emission computed tomography (SPECT) in patients with NSTACS managed with a conservative approach is uncertain, as most of the information derives from patients with chronic coronary artery disease. Objectives: 1) To analyze the outcomes of patients with NSTACS and LR SPECT at discharge, 2) to compare the results of a normal SPECT with transient perfusion defects (TPDs), permanent perfusion defects (PPDs) or combined defects (CDs), and 3) to determine the additional value of SPECT to classic risk variables. Material and Methods: Patients admitted to the CCU with a NSTACS were included. Follow-up was continued during 12 months. Definitions: Clinical risk based on TIMI risk score. LR SPECT (under exercise or pharmacological stress): TPDs ≤ 3/17 segments, PPDs ≤ 3/17 segments, CPDs: TPDs + PPDs and normal: absence of defects. Clinical events (CEs): death/infarction or rehospitalization due to angina. Results: A total of 137 patients were included (median age 59 years, 60% were men). A low TIMI risk score was present in 54% of patients and 46% presented a moderate risk. CE: 5.8%. The incidence of clinical events related to perfusion defects was as follows: normal: 2.1%, TPD: 4.5%, PPD: 5.9% and CPD: 25% (p [es

    2017-06-01

    The aim of the present study was to investigate the prognostic value of geriatric conditions beyond age after acute coronary syndrome. This was a prospective cohort design including 342 patients (from October 1, 2010, to February 1, 2012) hospitalized for acute coronary syndrome, older than 65 years, in whom 5 geriatric conditions were evaluated at discharge: frailty (Fried and Green scales), comorbidity (Charlson and simple comorbidity indexes), cognitive impairment (Pfeiffer test), physical disability (Barthel index), and instrumental disability (Lawton-Brody scale). The primary end point was all-cause mortality. The median follow-up for the entire population was 4.7 years (range, 3-2178 days). A total of 156 patients (46%) died. Among the geriatric conditions, frailty (Green score, per point; hazard ratio, 1.11; 95% CI, 1.02-1.20; P=.01) and comorbidity (Charlson index, per point; hazard ratio, 1.18; 95% CI, 1.0-1.40; P=.05) were the independent predictors. The introduction of age in a basic model using well-established prognostic clinical variables resulted in an increase in discrimination accuracy (C-statistic=.716-.744; P=.05), though the addition of frailty and comorbidity provided a nonsignificant further increase (C-statistic=.759; P=.36). Likewise, the addition of age to the clinical model led to a significant risk reclassification (continuous net reclassification improvement, 0.46; 95% CI, 0.21-0.67; and integrated discrimination improvement, 0.04; 95% CI, 0.01-0.09). However, the addition of frailty and comorbidity provided a further significant risk reclassification in comparison to the clinical model with age (continuous net reclassification improvement, 0.40; 95% CI, 0.16-0.65; and integrated discrimination improvement, 0.04; 95% CI, 0.01-0.10). In conclusion, frailty and comorbidity are mortality predictors that significantly reclassify risk beyond age after acute coronary syndrome.

    Background- Adaptive immune-response is associated with a worse outcome in acute coronary syndromes. Statins have anti-inflammatory activity beyond lowering lipid levels. We investigated the effects of ex-vivo and in-vivo atorvastatin treatment in acute coronary syndromes on CD4+T-cells, and the underlying molecular mechanisms.Approach and results- Blood samples were collected from 50 statin-naïve acute coronary syndrome patients. We assessed CD4+T-cell activation by flow-cytometry, the expression of 84 T-helper transcription-factors and 84 T-cell related genes by RT-qPCR, and protein expression by Western-blot, before and after 24-hours incubation with increasing doses of atorvastatin: 3-10-26 μg/ml (corresponding to blood levels achieved with doses of 10-40-80 mg, respectively). After incubation, we found a significant decrease in interferon-γ-producing CD4+CD28nullT-cells (P = 0.009) and a significant increase in interleukin-10-producing CD4+CD25highT-cells (P 3-fold changes).The in-vivo effects of atorvastatin were analyzed in 10 statin-free acute coronary syndrome patients at baseline, and after 24h and 48h of atorvastatin therapy (80 mg/daily): EGR1-gene expression decreased at 24h (P = 0.01) and 48h (P = 0.005); EGR1-protein levels decreased at 48h (P = 0.03).Conclusions-In acute coronary syndromes, the effects of atorvastatin on immune system might be partially related to the inhibition of the master regulator gene EGR1. Our finding might offer a causal explanation on why statins improve the early outcome in acute coronary syndromes.

    Whether the severity of left main coronary artery (LMCA) disease reflects LMCA and overall coronary atherosclerotic burden is not known. We aimed to assess nonculprit LMCA disease characteristics and the relationship with atherosclerosis in the rest of the coronary arteries as well as patient outcomes. In the PROSPECT study, 697 patients with acute coronary syndromes underwent three-vessel gray-scale and radiofrequency intravascular ultrasound after percutaneous coronary intervention. Overall, 552 patients with adequate LMCA imaging were compared according to LMCA plaque burden. The tertile with the highest plaque burden in the LMCA had the smallest LMCA minimum lumen area (17.4, 14.2, 10.5, lowest through highest tertiles, respectively, PPROSPECT predictors of future nonculprit major adverse cardiac events (MACE) (minimum lumen area≤4 mm, plaque burden≥70%, and virtual histology thin-cap fibroatheroma), the tertile with the highest LMCA plaque burden had the highest number of patients with at least one of three PROSPECT predictors (P=0.03). In multivariable model, though total atheroma volume (per 1%) was an independent predictor of all MACE [hazard ratio (95% confidence interval)=1.06 (1.01-1.11), P=0.02] and strong trend for non-culprit-related MACE [hazard ratio (95% confidence interval)=1.06 (1.00-1.13), P=0.06], plaque burden at LMCA was not (all MACE, P=0.90, non-culprit-related MACE, P=0.85). The severity of atherosclerosis in LMCA predicted the overall atherosclerotic plaque burden as well as the presence of high-risk plaques in the three major epicardial coronary arteries.

    There is a preponderance of evidence implicating diabetes with increased coronary artery disease (CAD) and calcification (CAC) in human patients with metabolic syndrome (MetS), but the effect of diabetes on CAD severity in animal models remains controversial. We investigated whether diabetes exacerbates CAD/CAC and intracellular free calcium ([Ca 2+ ] i ) dysregulation in the clinically relevant Ossabaw miniature swine model of MetS. Sixteen swine, eight with alloxan-induced diabetes, were fed a hypercaloric, atherogenic diet for 6 months. Alloxan-induced pancreatic beta cell damage was examined by immunohistochemical staining of insulin. The metabolic profile was confirmed by body weight, complete blood panel, intravenous glucose tolerance test (IVGTT), and meal tolerance test. CAD severity was assessed with intravascular ultrasound and histology. [Ca 2+ ] i handling in coronary smooth muscle (CSM) cells was assessed with fura-2 ratiometric imaging. Fasting and post-prandial blood glucose, total cholesterol, and serum triglycerides were elevated in MetS-diabetic swine. This group also exhibited hypoinsulinemia during IVGTT and less pancreatic beta cell mass when compared to lean and MetS-nondiabetic swine. IVUS analysis revealed that MetS-diabetic swine had greater percent wall coverage, percent plaque burden, and calcium index when compared to lean and MetS-nondiabetic swine. Fura-2 imaging of CSM [Ca 2+ ] i revealed that MetS-nondiabetic swine exhibited increased sarcoplasmic reticulum Ca 2+ store release and Ca 2+ influx through voltage-gated Ca 2+ channels compared to lean swine. MetS-diabetic swine exhibited impaired Ca 2+ efflux. Diabetes exacerbates coronary atherosclerosis and calcification in Ossabaw miniature swine with MetS, accompanied by progression of [Ca 2+ ] i dysregulation in advanced CAD/CAC. These results recapitulate increased CAD in humans with diabetes and establish Ossabaw miniature swine as an animal model for future Met

    Full Text Available Objective: To assess the cost-effectiveness relationship of Ticagrelor versus Clopidogrel for the management of acute coronary syndrome in Spain. Methods: The data from the PLATO study were used for the calculation of the events rate and health-related quality of life for Ticagrelor and Clopidogrel for the first 12 months, whereas the costs were obtained from Spanish sources. Quality of lifeadjusted survival and costs were estimated according to the fact that the patients did not suffer any thrombotic event (myocardial infarction or ictus or this one was not fatal. The lifetime cots, life years gained, and the quality of life-adjusted survival were estimated for both treatment arms. Incremental costeffectiveness ratios were assessed through the perspective of the Spanish healthcare system for 2013, by using a macro-costs strategy based on published literature and the survival tables for the Spanish population. Results: Treatment with Ticagrelor was associated to an incremental cost of 1,228 per year, an increase in 0.1652 life years gained, and 0.1365 years adjusted by quality of life, as compared to Clopidogrel. The cost for one quality of life-adjusted life year was 8,997 and the cost per one gained life year of 7,435 . The sensitivity analysis showed consistent results. Conclusions: Treatment of acute coronary syndrome for 12 months with Ticagrelor was associated with a cost per 1 life year of quality of life-adjusted cost below the cost-effectiveness limits generally accepted in Spain.

    BACKGROUND: Metabolic syndrome (MS) is associated with subsequent development of type 2 diabetes and cardiovascular disease in the general population. The impact of MS on mortality in patients with stable coronary heart disease is less well defined, and the association of prognosis to gender...... follow-up of 9.2 years. RESULTS: At follow-up 296 (28%) patients had died. 315 (30%) patients had MS based on the definition by the World Health Organization. Patients with MS more frequently had diabetes and three-vessel disease of the coronary arteries. Men had a more severe risk profile than women....... In a multivariable Cox regression analysis, MS was not associated with excess mortality risk in the overall population [adjusted HR=1.3 (95% CI: 0.7-2.3), p=0.43]. In gender specific analyses MS increased risk of all-cause mortality in women [adjusted HR=2.2 (95% CI: 1.1-4.3), p=0.02], but not in men [adjusted HR=1...

    Serum fibrinogen level (SF) is thought to be one of the risk factors for coronary artery disease (CAD). The purpose of this study was to measure the SFL in patients with acute coronary syndrome (ACS). This study was performed in patients with ACS, admitted in Shahid Beheshti Hospital, Babol, Iran, from February 2005 to June 2006. Two hundred patients with ACS were divided into 4 groups: Group I - ST elevated myocardial infarction (STEMI); Group II - non-ST elevated myocardial infarction (NSTEMI), Group III - unstable angina (U/A) with ST-T change and Group IV: U/A without ST-T change. Each group includes 50 patients. Twenty-four hours after admission, the SFL was measured using chromatography methods. The data were collected and analyzed. The mean SFL per mg/dl in each group are Group I - 377.8+-28, Group II - 417.2+-26.8, Group III - 335.4+-19.8 and Group IV - 305.1+-13.8. The SFL in Group II was significantly higher in the other group (p=0.002). The SFL in Group II was higher than in Group III (p=0.02) and much higher than in Group IV (p=0.000). The SFL in Group III was more than in Group IV (p=0.018). The results show that SFL is an important marker in patients with ACS, with ST-T change. (author)

    Objective: To evaluate analysis of clinical application on determining serum inflammatory cytokines levels in patients with acute coronary syndrome (ACS). Methods: The levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-8 (IL-8), high-sensitive C-reaction protein (hs-CRP) (with high-sensitive enzyme immunoassay) and tumor necrosis factor-α (TNF-α) (with radioimmunoassay) in serum were determined in 112 patients with ACS, 32 patients with stable angina pectoris (SAP) and 42 normal controls as well as did compared analysis. Results: The serum IL-1β, IL-6, IL-8, TNF-α and hs-CRP levels in 112 patients with ACS were obviously higher than those in 42 controls (P all 0.05), serum hs-CRP level was increased only (P<0.05). The serum IL-1β, IL-6, IL-8, TNF-α and hs-CRP levels in 46 patients with acute myocardial infraction (AMI) were prominently higher than those in 66 patients with unstable angina pectoris (UAP) and in 32 patients with SAP. The serum IL-1β, IL-6, IL-8, TNF-α and hs-CRP levels with advanced degree SAP, UAP and AMI were increased. Conclusion: In the severity of the patients with SAP, UAP, AMI, the determination of serum inflammatory cytokines level were a good and important index, so that it was referential for heart coronary events happened.

    The term acute coronary syndrome (ACS) encompasses a range of thrombotic coronary artery diseases, including unstable angina (UA) and both ST-segment elevation (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI). Bio markers play an important role in the diagnosis of non-ST-elevation ACS (NSTE-ACS) including unstable angina and non-STEMI. Among these, cardiac troponin and creatine phosphokinase myocardial band appeared to be the most sensitive and specific markers of myocardial injury. The important role of inflammatory processes in the development and progression of atherosclerosis has been clearly established. Different circulating inflammatory bio markers indicating the instability of atherosclerotic plaque have been identified and serve as diagnostic tools for the identification of patients with unstable angina or acute myocardial infarction and to identify risk patients. The present study was carried out on twenty patients with (NSTE-ACS). The level of serum troponin I (cTnI), creatine phosphokinase-total (CPK-T), myocardial band of creatine phosphokinase (CPK-MB), pregnancy associated plasma protein-A (PAPP-A) and highly sensitive C-reactive protein (hsCRP) were determined. The results showed increase in the level of cardiac bio markers (cTnI, CPK-MB, CPK-T) and inflammatory markers (PAPP-A, hsCRP). It could be concluded that the increase in inflammatory markers correlate especially PAPP-A in NSTE-ACS with the increase of cardiac bio markers

    Patients with diabetes mellitus (DM) and acute coronary syndromes have a greater level of platelet aggregation and a poor response to oral antiplatelet drugs. Clopidogrel is still widely used in clinical practice, despite the current evidence favoring ticagrelor and prasugrel. The aim of this study was to investigate the determinants of clopidogrel use in the population of the multicenter prospective 'Acute Coronary Syndrome and Diabetes Registry' carried out during a 9-week period between March and May 2015 at 29 Hospitals. A total of 559 consecutive acute coronary syndrome patients [mean age: 68.7±11.3 years, 50% ST-elevation myocardial infarction (STEMI)], with 'known DM' (56%) or 'hyperglycemia' at admission, were included in the registry; 460 (85%) patients received a myocardial revascularization. At hospital discharge, dual antiplatelet therapy was prescribed to 88% of the patients (clopidogrel ticagrelor and prasugrel to 39, 38, and 23%, respectively). Differences in P2Y12 inhibitor administration were recorded on the basis of history of diabetes, age, and clinical presentation (unstable angina/non-STEMI vs. non-STEMI). On univariate analysis, age older than 75 years or more, known DM, peripheral artery disease, previous myocardial infarction, previous revascularization, complete revascularization, previous cerebrovascular event, creatinine clearance, unstable angina/non-STEMI at presentation, Global Registry of Acute Coronary Events Score, EuroSCORE, CRUSADE Bleeding Score, and oral anticoagulant therapy were significantly associated with clopidogrel choice at discharge. On multivariate analysis, only oral anticoagulant therapy and the CRUSADE Bleeding Score remained independent predictors of clopidogrel prescription. In the present registry of a high-risk population, clopidogrel was the most used P2Y12 inhibitor at hospital discharge, confirming the 'paradox' to treat sicker patients with the less effective drug. Diabetic status, a marker of higher

    Clopidogrel has become standard treatment after urgent percutaneous coronary revascularization. Due to its enhanced and irreversible platelet inhibition, patients undergoing urgent surgical revascularization have a higher risk of bleeding complications and transfusions. Therefore, the effect of preoperative continuous administration of clopidogrel on the incidence of hemorrhagic complications in patients undergoing off-pump coronary artery bypass surgery with acute coronary syndrome was evaluated. From March 2004 to September 2006, 172 patients with acute coronary syndrome underwent isolated off-pump coronary artery bypass surgery; 70 (40.7%) and 102 (59.3%) of these patients did or did not take clopidogrel before surgery respectively. Seventy patients in each group were matched using propensity scores and associations between preoperative continuous administration of clopidogrel and postoperative bleeding, hemostatic reoperation, blood products received, the need for multiple transfusions and early graft patency by coronary computed tomography were assessed. Univariate analysis showed the continuous clopidogrel group had similar levels of postoperative bleeding for 24 h (601.4±312.6 ml vs 637.2±452.4 ml, p=0.616) and rates of reexploration (1.4% vs 1.4%), perioperative blood transfusion (33.3% vs 34.3%, p>0.05) and platelet transfusion (2.9% vs 7.1%, p=0.44) compared with the non-continuous group. Preoperative continuous administration of clopidogrel did not increase the risk of hemorrhagic complications in patients with acute coronary syndrome undergoing isolated off-pump coronary artery bypass surgery. These findings indicate that surgery after clopidogrel treatment in patients with acute coronary syndrome should not be delayed until platelet function returns to normal because they may have a higher risk of recurrent myocardial ischemic events.

    Full Text Available Introduction: Metabolic syndrome (MS is considered as an important risk factor for advanced coronary artery disease. This condition can increase the mortality and morbidity in the patients undergoing coronary artery bypass graft (CABG surgery. The aim of the study was compared mortality and morbidity after off Pump- CABG surgery between patients with and without the Metabolic syndrome. Materials & Methods: This prospective cross-sectional study was conducted on 120 patients, who underwent off-pump CABG surgery between October 2014-October 2016. The participants were equally divided into two groups including the patients with and without MS (MS and non-MS, respectively. Results: According to the results, 68 (56.6% patients were male. Furthermore, out of the 60 participants with MS, 36 (60% cases were male. The mean ages of the MS and non-MS groups were 64.96±9.6 and 65.62±10.6 P=0.6 years, respectively. No statistically significant difference was observed between the two groups in terms of the mortality and morbidity (e.g., surgical wound infection, length of Intensive Care Unit and hospital stay, atrial fibrillation rhythm, and bleeding in the first 24 h. The intubation time in patients with Metabolic Syndrome was significantly higher than patients without Metabolic Syndrome (6.66 ± 1.97 vs 5.83 ± 1.93 respectively; P=0.007 Conclusion: Metabolic syndrome was not associated with higher mortality and morbidity after CABG surgery compare to patients without Metabolic syndrome, although patients with Metabolic syndrome had higher risk for long intubation time.

    Many meta-analyses have provided synthesised likelihood ratio data to aid clinical decision-making. However, much less has been published on how to safely combine clinical information in practice. We aimed to explore the benefits and risks of pooling clinical information during the ED assessment of suspected acute coronary syndrome. Clinical information on 1776 patients was collected within a randomised trial conducted across five South Australian EDs between July 2011 and March 2013. Bayes theorem was used to calculate patient-specific post-test probabilities using age- and gender-specific pre-test probabilities and likelihood ratios corresponding to the presence or absence of 18 clinical factors. Model performance was assessed as the presence of adverse cardiac outcomes among patients theoretically discharged at a post-test probability less than 1%. Bayes theorem-based models containing high-sensitivity troponin T (hs-troponin) outperformed models excluding hs-troponin, as well as models utilising TIMI and GRACE scores. In models containing hs-troponin, a plateau in improving discharge safety was observed after the inclusion of four clinical factors. Models with fewer clinical factors better approximated the true event rate, tended to be safer and resulted in a smaller standard deviation in post-test probability estimates. We showed that there is a definable point where additional information becomes uninformative and may actually lead to less certainty. This evidence supports the concept that clinical decision-making in the assessment of suspected acute coronary syndrome should be focused on obtaining the least amount of information that provides the highest benefit for informing the decisions of admission or discharge. © 2017 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    Oxidative stress plays a major role in the development of atherosclerosis. However, the relationship between oxidative stress and complexity and intensity of coronary artery disease is less clear. The aim of this study is to assess the relationship between oxidative stress markers and the complexity and intensity of coronary artery disease in patients with acute coronary syndrome (ACS). Sixty-seven consecutive patients with an early phase of ACS (=22). Likewise patients were divided into two CAD severity groups according to the median Gensini score of 64: less intensive CAD with Gensini score (=64. Blood samples were taken in 1 hour within administration in order to measure total oxidative status (TOS) and total antioxidant capacity (TAC) levels determined by Erel method. Oxidative stress index (OSI) was calculated by TOS /TAC. There was no significant difference between the two SYNTAX groups for oxidative stress markers. Median TOS and OSI values were significantly high in the intensive CAD group (p=0.005, p=0.04, respectively). The Gensini score was positively correlated with TOS and OSI (p=0.003, p=0.02, respectively). Oxidative stress markers may be considered supportive laboratory parameters related to CAD intensity but not complexity in ACS patients.

    This study was designed to determine whether coronary CT angiography (CTA) can detect features of plaque disruption in clinically stable patients and to compare lesion prevalence and features between stable patients and those with acute coronary syndrome (ACS). We retrospectively identified patients undergoing CTA, followed by invasive coronary angiography (ICA) within 60 days. Quantitative 3-vessel CTA lesion analysis was performed on all plaques ≥25% stenosis to assess total plaque volume, low attenuation plaque (LAP, disruption, including ulceration and intra-plaque dye penetration (IDP). ICA was employed as a reference standard for disruption. A total of 145 (94 ACS and 51 stable) patients were identified. By CTA, plaque disruption was evident in 77.7% of ACS cases. Although more common among those with ACS, CTA also detected plaque disruption in 37.3% of clinically stable patients (P disruption as determined by CTA. Though the prevalence of plaque disruption is less than patients with ACS, these findings support the concept that some clinically stable patients may harbour 'silent' disrupted plaques. These findings may have implications for detection of 'at risk' plaques and patients. Published on behalf of the European Society of Cardiology. All rights reserved. © The Author 2015.

    Purpose: To prospectively investigate the coronary artery status using coronary CT angiography (CCTA) in patients with Hodgkin lymphoma treated with combined modalities and mediastinal irradiation. Methods and Materials: All consecutive asymptomatic patients with Hodgkin lymphoma entered the study during follow-up, from August 2007 to May 2012. Coronary CT angiography was performed, and risk factors were recorded along with leukocyte telomere length (LTL) measurements. Results: One hundred seventy-nine patients entered the 5-year study. The median follow-up was 11.6 years (range, 2.1-40.2 years), and the median interval between treatment and the CCTA was 9.5 years (range, 0.5-40 years). Coronary artery abnormalities were demonstrated in 46 patients (26%). Coronary CT angiography abnormalities were detected in nearly 15% of the patients within the first 5 years after treatment. A significant increase (34%) occurred 10 years after treatment (P=.05). Stenoses were mostly nonostial. Severe stenoses were observed in 12 (6.7%) of the patients, entailing surgery with either angioplasty with stent placement or bypass grafting in 10 of them (5.5%). A multivariate analysis demonstrated that age at treatment, hypertension, and hypercholesterolemia, as well as radiation dose to the coronary artery origins, were prognostic factors. In the group of patients with LTL measurements, hypertension and LTL were the only independent risk factors. Conclusions: The findings suggest that CCTA can identify asymptomatic individuals at risk of acute coronary artery disease who might require either preventive or curative measures. Conventional risk factors and the radiation dose to coronary artery origins were independent prognostic factors. The prognostic value of LTL needs further investigation.

    The study sought to examine the relative importance of lesion location versus vessel area and plaque burden in predicting plaque rupture within nonculprit fibroatheromas (FAs) in patients with acute coronary syndromes. Previous studies have demonstrated that plaque rupture is associated with larger vessel area and greater plaque burden clustering in the proximal segments of coronary arteries. In the PROSPECT (Providing Regional Observations to Study Predictors of Events in the Coronary Tree) study 3-vessel grayscale and radiofrequency-intravascular ultrasound was performed after successful percutaneous coronary intervention in 697 patients with acute coronary syndromes. Untreated nonculprit lesion FAs were classified as proximal (40 mm) according to the distance from the ostium to the maximum necrotic core site. Overall, 74 ruptured FAs and 2,396 nonruptured FAs were identified in nonculprit vessels. The majority of FAs (73.6%) were located within 40 mm of the ostium, and the vessel area and plaque burden progressively decreased from proximal to distal FA location (both p PROSPECT]; NCT00180466).

    Health emergency service teams play an important role in the management of patients with acute coronary syndrome. They have to be educated, equipped, skilful and supported by the entire health care system. The role of county health center in the management of patients with acute coronary syndrome is illustrated in the article, based on the experience acquired at Medimurje County Health Center from Cakovec. The reformed Health Center activities including organization, coordination and linking of teams, population health monitoring at the local level, epidemiologic surveillance, education (active and passive, on both sides of college chair), joint diagnostic and other services, and quality control are discussed in detail. In contrast to a bureaucratic and formal one, a real and innovative reform should take account of necessary changes in the management and organization, not just in standards, rights and obligations. The management protocol for acute coronary syndrome patients is described: setting the main objective (acute coronary disease morbidity and mortality reduction), setting short-term and long-term specific goals, adoption of strategy based on the main objective (education, completion and particular programs pursuit, connecting, collaboration, quality assurance through clinical guidelines and protocols) and other elements, including dignity, leadership, teamwork, adoption and implementation of patient management protocols.

    The aim was to characterise acute coronary syndrome patients with complete atrioventricular block and to assess the effect on outcome. Patients admitted with acute coronary syndrome were divided according to the presence of complete atrioventricular block: group 1, with complete atrioventricular block; group 2, without complete atrioventricular block. Clinical, electrocardiographic and echocardiographic characteristics and prognosis during one year follow-up were compared between the groups. Among 4799 acute coronary syndrome patients admitted during the study period, 91 (1.9%) presented with complete atrioventricular block. At presentation, group 1 patients presented with lower systolic blood pressure, higher Killip class and incidence of syncope. In group 1, 86.8% presented with ST-segment elevation myocardial infarction (STEMI), and inferior STEMI was verified in 79.1% of patients in group 1 compared with 21.9% in group 2 ( Pblock was observed in 7.3% in contrast to 2.5% in patients submitted to primary percutaneous coronary intervention ( Pblock was an independent predictor of hospital mortality (odds ratio 3.671; P=0.045). There was no significant difference in mortality at one-year follow-up between the study groups. Complete atrioventricular block conferred a worse outcome during hospitalisation, including a higher incidence of cardiogenic shock, ventricular arrhythmias and death.

    Objective: To determine the correlation of C-reactive protein (CRP) levels with the severity of coronary stenosis on angiography and the association of cardiac enzymes with the degree of stenosis in acute coronary syndrome (ACS) patients. Secondly, to compare association of angiographic severity of vascular stenosis with CRP in patients with ST segment elevation myocardial infarction (STEMI) and non-STEMI / Unstable angina (UA). Study Design: Prospective, descriptive study. Place and Duration of Study: Khan Research Laboratories (KRL) Hospital, from October 2014 to March 2015. Methodology: CRP was measured on diagnosis of ACS in 70 patients. Cardiac enzymes were measured 6 hours after the onset of chest pain. Angiographic scoring for degree of stenosis and number of culprit vessels was done. Two groups consisting of patients with STEMI (group 1) and with NSTEMI/UA (group 2) were made. Results: No correlation was found between CRP levels and angiographic stenosis in patients with ACS (r=0.162, p>0.05). No association was found between eosinophil count and severity of stenosis (p=0.88). Rise of cardiac enzymes and degree of coronary stenosis showed a positive correlation (p <0.001). There was significant difference in the means of coronary artery stenosis scores between the two groups (Gensini score of groups 1 and 2: 35.9 +- 4 and 14 +- 8, respectively) p<0.001, but there was no significant difference in CRP levels. Conclusion: CRP is a marker of inflammation in ACS rather than a risk factor for determining the severity of vascular stenosis. Rise in cardiac enzymes still grade high in predicting severity of vascular stenosis than eosinophil count or CRP levels. (author)

    Full Text Available Coronary artery disease (CAD is the leading causes of deaths in the world. The differentiation of syndrome (ZHENG is the criterion of diagnosis and therapeutic in TCM. Therefore, syndrome prediction in silico can be improving the performance of treatment. In this paper, we present a Bayesian network framework to construct a high-confidence syndrome predictor based on the optimum subset, that is, collected by Support Vector Machine (SVM feature selection. Syndrome of CAD can be divided into asthenia and sthenia syndromes. According to the hierarchical characteristics of syndrome, we firstly label every case three types of syndrome (asthenia, sthenia, or both to solve several syndromes with some patients. On basis of the three syndromes’ classes, we design SVM feature selection to achieve the optimum symptom subset and compare this subset with Markov blanket feature select using ROC. Using this subset, the six predictors of CAD’s syndrome are constructed by the Bayesian network technique. We also design Naïve Bayes, C4.5 Logistic, Radial basis function (RBF network compared with Bayesian network. In a conclusion, the Bayesian network method based on the optimum symptoms shows a practical method to predict six syndromes of CAD in TCM.

    Full Text Available Abstract Background Despite continual improvements in the management of acute coronary syndromes, adherence to guideline-based medications remains suboptimal. We aim to improve adherence with guideline-based therapy following acute coronary syndrome using an existing service that is provided by specifically trained pharmacists, called a Home Medicines Review. We have made two minor adjustments to target the focus of the existing service including an acute coronary syndrome specific referral letter and a training package for the pharmacists providing the service. Methods/Design We will be conducting a randomized controlled trial to compare the directed home medicines review service to usual care following acute coronary syndromes. All patients aged 18 to 80 years and with a working diagnosis of acute coronary syndrome, who are admitted to two public, acute care hospitals, will be screened for enrolment into the trial. Exclusion criteria will include: not being discharged home, documented cognitive decline, non-Medicare eligibility, and presence of a terminal malignancy. Randomization concealment and sequence generation will occur through a centrally-monitored computer program. Patients randomized to the control group will receive usual post-discharge care. Patients randomized to receive the intervention will be offered usual post-discharge care and a directed home medicines review at two months post-discharge. The study endpoints will be six and twelve months post-discharge. The primary outcome will be the proportion of patients who are adherent to a complete, guideline-based medication regimen. Secondary outcomes will include hospital readmission rates, length of hospital stays, changes in quality of life, smoking cessation rates, cardiac rehabilitation completion rates, and mortality. Discussion As the trial is closely based on an existing service, any improvements observed should be highly translatable into regular practice. Possible

    Full Text Available Background. Recent intravascular ultrasound (IVUS studies have demonstrated that hypoechoic plaque with deep ultrasound attenuation despite absence of bright calcium is common in acute coronary syndrome. Such “attenuated plaque” may be an IVUS characteristic of unstable lesion. Methods. We used optical coherence tomography (OCT in 104 patients with unstable angina to compare lesion characteristics between IVUS-detected attenuated plaque and nonattenuated plaque. Results. IVUS-detected attenuated plaque was observed in 41 (39% patients. OCT-detected lipidic plaque (88% versus 49%, <0.001, thin-cap fibroatheroma (48% versus 16%, <0.001, plaque rupture (44% versus 11%, <0.001, and intracoronary thrombus (54% versus 17%, <0.001 were more often seen in IVUS-detected attenuated plaques compared with nonattenuated plaques. Conclusions. IVUS-detected attenuated plaque has many characteristics of unstable coronary lesion. The presence of attended plaque might be an important marker of lesion instability.

    Full Text Available We describe the unexpected case of a 70-year-old man, with medical history of ischemic heart disease and surgery for aneurysm of abdominal aorta, who comes to the emergency department complaining of low-back pain without other symptoms or signs of organic failure. After a few hours we see a deterioration of physical conditions with pulmonary oedema, increase of blood pressure, changing in the ECG pattern, and worsening of left ventricular function with progressive increase of biomarkers for myocardial necrosis. So this pain has revealed the premature symptom of an acute coronary syndrome (ACS. After a short time a subsequent cardiac arrest complicates the clinical situation. After resuscitation, the patient undergoes successfully to coronary angiography and performed a percutaneous transluminal coronary angioplasty (PTCA.

    After childhood Kawasaki syndrome (KS) the coronary arteries undergo a lifelong dynamic pathological change, and follow-up coronary artery imaging is essential. At present, conventional coronary catheterization (CCC) and angiography is still regarded as the gold standard. Less-invasive methods such as multidetector CT angiography (MDCT-A) and MRI have been used sporadically. To compare the diagnostic quality of MDCT-A and MRI with that of CCC for coronary imaging in a group of patients with coronary artery pathology after childhood KS. A total of 16 patients (aged 5-27 years) underwent CCC and 16-row MDCT-A and 14 patients MRI (1.5 T). There was 100% agreement between MDCT-A and CCC in the detection of coronary aneurysms and stenoses. MDCT-A was superior for the visualization of calcified lesions. MRI and CCC showed 93% agreement for the detection of aneurysms. Visualization of coronary artery stenoses was difficult using MRI - one stenosis was missed. MDCT-A has excellent correlation with CCC regarding all changes affecting the coronary arteries in the follow-up of childhood KS. In comparison to MDCT-A and CCC, MRI is less precise in the detection of stenotic lesions. Due to its high image quality and ease of performance MDCT-A should be the primary diagnostic modality in patients following childhood KS. (orig.)

    Acute Coronary Syndrome (ACS), is a serious threat to people's health, and life, and in recent years, the incidence has increased yearly. This study was to propose the hypothesis of "endogenous collateral wind" based on the patho-mechanism of thrombogenesis complicated by ruptured plaque on ACS, and the theory of traditional Chinese medicine. Through successful coronary angiography (CAG), and intravascular ultrasound (IVUS), patients with coronary artery disease were made the differential diagnosis such as blood stasis, blood stasis due to phlegm obstruction, and endogenous collateral wind. The levels of plasma inflammatory marker were measured to study on the characteristics of "endogenous collateral wind". Luo heng dripping pills with promoting blood circulation to expel wind-evil, and remove wetness were made based on the hypothesis of "endogenous collateral wind" on ACS. Patients with unstable angina were randomly divided into 3, groups based on therapeutic methods: conventional therapy group, Luo Heng dripping pills group and Tongxinluo caps. Differences among groups were compared. There were great changes in number and degree of coronary arteriostenosis confirmed by CAG, the types of ACC/AHA lesion and Levin lesion confirmed by CAG, remodeling index, positive or negative remodeling percentage measured by IVUS, the plasma levels of plasma inflammatory marker measured by ELLSA in the patients with endogenous collateral wind, compared with patients with blood stasis and blood stasis due to phlegm obstruction. The total effective rate of improved angina in Luo Heng dripping pills group was significantly higher than those in other two groups. The levels of plasma inflammatory marker were significantly lower in Luo Heng dripping pills group. There were some pathological basis which were found about the hypothesis of "endogenous collateral wind" on acute coronary syndrome. It provided evidences for patients with coronary artery disease treated by medicines with

    Background and aims: Cardiovascular disease (CVD) is the leading cause of death in the Middle East. We sought to study the prevalence and coexistence of 6 cardiovascular risk factors (RFs) among patients who underwent percutaneous coronary intervention (PCI), and to evaluate the impact of age and gender on the presence of multiple RFs. In this prospective, multicenter study, 2426 consecutive patients were enrolled. Mean age was 59.0 ± 10.1 years and 500 (20.6%) were women. Acute coronary syndrome and stable coronary disease were the indications for PCI in 77.1% and 22.9%, respectively. Hypertension was present in 62.3%, diabetes in 53.8%, hypercholesterolemia in 48.8%, smoking in 43.5%, family history of premature CVD 39.4% and obesity in 28.8%. Only 3.8% did not have any of these RFs. Presence of ⩾3 and ⩾4 RFS was observed in 57.4% and 29.5% of patients, respectively. Presence of ⩾3 RFs was more common in women than men (69.0% vs. 54.5%, p  Eastern population undergoing PCI. More than half and more than one-fourth of the patients had at least 3 or 4 RFs; respectively. More women than men and more middle aged patients than older or younger patients had significantly higher rates of presence of multiple RFs.

    The objective was to investigate the efficacy of a magnetic navigation system (MNS) in a coronary phantom. The number of coronary interventional procedures performed is steadily increasing with the availability of new devices to treat more complex lesions. Vessel tortuosity remains an important limiting factor in percutaneous coronary intervention. The MNS can orient the tip of magnetized wire. The coronary phantom is a representation of the coronary tree. Two operators using both a magnetic wire and a standard wire, measured the procedural time (PT), the fluoroscopic time (FT) and the radiation exposure/area product (DAP) required to navigate through to fourteen segments. Ten wire advancements were performed per segment. In all but two segments, the PT was significantly longer using magnetic navigation than using manual navigation. The median FT in the left main artery (LMA) - first septal segment was 7 seconds vs. 18 seconds, with magnetic and manual navigation respectively, (p=0.05); in the LMA - obtuse marginal segment the median FT was 15 seconds with magnetic navigation vs. 29.5 seconds with manual navigation, (p=0.01); in the segment from proximal right coronary artery (RCA1) to the acute marginal branch, the median FT was 8 seconds with magnetic vs. 11 seconds with manual navigation, (p=0.05); and in the RCA1 -posterior descending segment the median FT was 9.5 seconds with magnetic vs. 15 seconds with manual navigation, (p=0.006). The MNS facilitates wire access to distal segments in a coronary phantom, with a reduction in FT and radiation exposure using magnetic navigation in tortuous segments.

    Full Text Available The objective was to determine the rate of potential drug-drug interactions in prescriptions for elderly diagnosed with Acute Coronary Syndrome in a teaching hospital. This is an exploratory, descriptive study that analyzed 607 prescriptions through databases to identify and classify the interactions based on intensity (major, moderate or minor, the mechanism (pharmacokinetic or pharmacodynamics and documentation relevance. We detected 10,162 drug-drug interactions, distributed in 554 types of different combinations within the prescribed drugs, and 99% of prescriptions presented at least one and a maximum of 53 interactions; highlighting the prevalence of major and moderates ones. There was a correlation between the number of drug-drug interactions and the number of prescribed drugs and the hospitalization time. This study contributes for the delimitation of a prevalence pattern in drug-drug interactions in prescriptions for Acute Coronary Syndrome, besides subsidizing the importance of the effective implementation of the Clinical Pharmacy in teaching hospitals.

    Atherosclerotic cardiovascular disease is an epidemic in today's world. It is one of the most common causes of hospitalization and death. Therefore, remedies to control or heal the disease are continuously sought. In addition to scientifically researched therapies, patients frequently utilize alternative medicine. However, effective and toxic doses, metabolisms, and drug interactions of the herbs and herbal nutrition supplements are largely unknown. Herein, we present two cases with acute coronary syndrome. The first case was admitted with a diagnosis of acute inferior myocardial infaction (MI) and a stent was implanted to the occluded right coronary artery (RCA). There was a 50% stenosis in his left anterior descending artery (LAD). He was admitted with a diagnosis of non-ST elevation MI (NSTEMI) 6 months later. In the coronary angiogram, there was stent restenosis in RCA, the lesion in LAD had become thrombotic and progressed to a stenosis of 90%. He was referred to surgical revascularization. The second case was admitted for acute inferior MI and a stent was implanted to the occluded circumflex artery. Two months later, he was hospitalized for NSTEMI. Progression of coronary plaques to stenosis and stent restenosis was detected and he was referred to surgical revascularization. Both patients used the product sold as Clavis Panax, which contains panax ginseng, tribulus terrestris, and oat, after their first coronary intervention. Intake of a mixture of plant extracts may have serious consequences in humans as drug interactions and side effects are unknown.

    Prior aspirin treatment is considered a risk factor for adverse outcomes in acute coronary syndrome (ACS) patients. The relationships between aspirin pretreatment and findings on quantitative coronary angiography (QCA) and intravascular ultrasound (IVUS), as well as clinical outcomes, are not well understood. In the PROSPECT trial, QCA and triple-vessel IVUS imaging were performed after successful percutaneous coronary intervention (PCI) of the culprit lesion(s) in ACS patients. We compared patients receiving aspirin within 7 days of enrollment to those naive to aspirin. Propensity score matching was performed to adjust for differences in baseline characteristics. Aspirin-pretreated patients (n = 236; 35%) were older and more likely to have known coronary disease than those without pretreatment (P≤.01 for all). Pretreated patients had more untreated non-culprit lesions with angiographic and IVUS characteristics predictive of future events (53.1% vs 38.6%; PPROSPECT trial, aspirin pretreatment identifies an older population with more advanced coronary disease. Aspirin pretreatment was not an independent predictor of MACE in ACS patients treated with an early invasive strategy. The extent to which aspirin pretreatment is a risk factor for adverse events after PCI in ACS should be revisited.

    Full Text Available Type 2 diabetes and prediabetes are established risk factors for atherosclerosis. The aim of this study was to evaluate the atherosclerotic plaque burden in the carotid arteries of patients with acute coronary syndrome according to their glycemic status.Patients with acute coronary syndrome and no previous history of type 2 diabetes were consecutively included in the study. Glucose metabolism was evaluated with fasting glucose in plasma, HbA1c and a standard two-hour oral glucose tolerance test. Atherosclerotic plaque in the carotid arteries was evaluated with a standardized ultrasound examination where total plaque area was measured and patients classified as having no plaque or a significant plaque formation.A total of 245 acute coronary syndrome patients (male 78%, 64 years (SD: 10.9 were included. The proportion diagnosed with normal glucose metabolism, prediabetes and type 2 diabetes was 28.6%, 64.1% and 7.3%, respectively. A significant atherosclerotic plaque was found in 48.5%, 66.9% and 72.2% of patients with normal glucose metabolism, prediabetes and type 2 diabetes, respectively. An incremental increase in total plaque area was found from normal glucose metabolism to prediabetes (25.5% and from normal glucose metabolism to type 2 diabetes (35.9% (p = 0.04. When adjusted for conventional cardiovascular risk factors the OR of having significant atherosclerotic plaque in the carotid arteries was 2.17 (95% CI 1.15-4.15 for patients with newly diagnosed dysglycemia compared to patients with normal glucose metabolism. When additionally adjusted for the 2-hour plasma glucose after glucose loading (2hPG the OR attenuated to 1.77 (95% CI 0.83-3.84.Newly detected dysglycemia is an independent predictor of significant atherosclerotic plaque in the carotid arteries with oral glucose tolerance test as a major determinant of carotid plaque burden in this group of individuals with acute coronary syndrome.

    Acute myocardial infarction is the leading cause of non-communicable deaths worldwide. Its diagnosis is a highly complex task, for which modelling through automated methods has been attempted. A systematic review of the literature was performed on diagnostic tests that applied intelligent systems tools in the diagnosis of acute coronary syndromes. A systematic review of the literature is presented using Medline, Embase, Scopus, IEEE/IET Electronic Library, ISI Web of Science, Latindex and LILACS databases for articles that include the diagnostic evaluation of acute coronary syndromes using intelligent systems. The review process was conducted independently by 2 reviewers, and discrepancies were resolved through the participation of a third person. The operational characteristics of the studied tools were extracted. A total of 35 references met the inclusion criteria. In 22 (62.8%) cases, neural networks were used. In five studies, the performances of several intelligent systems tools were compared. Thirteen studies sought to perform diagnoses of all acute coronary syndromes, and in 22, only infarctions were studied. In 21 cases, clinical and electrocardiographic aspects were used as input data, and in 10, only electrocardiographic data were used. Most intelligent systems use the clinical context as a reference standard. High rates of diagnostic accuracy were found with better performance using neural networks and support vector machines, compared with statistical tools of pattern recognition and decision trees. Extensive evidence was found that shows that using intelligent systems tools achieves a greater degree of accuracy than some clinical algorithms or scales and, thus, should be considered appropriate tools for supporting diagnostic decisions of acute coronary syndromes.

    Background In this study, we aimed to evaluate the effects of niacin on high sensitivity C reactive protein (hs-CRP) and cholesterol levels in non-ST elevated acute coronary syndrome (NSTE-ACS) patients. Methods In this prospective, open label study, 48 NSTE-ACS were randomized to niacin or control group. Patients continued their optimal medical therapy in the control group. In the niacin group patients were assigned to receive extended-release niacin 500 mg/day. Patients were contacted 1 month later to assess compliance and side effects. Blood samples for hs-CRP were obtained upon admittance to the coronary care unit, in the third day and in the first month of the treatment. Fasting blood samples for cholesterol levels were obtained before and 30 days after the treatment. The primary end point of the study was to evaluate changes in hs-CRP, cholesterol levels, short-term cardiovascular events, and the safety of niacin in NSTE-ACS. Results Baseline demographic, clinical and laboratory characteristics were similar between the two groups. Logarithmic transformation of baseline and 3rd day hs-CRP levels were similar between the groups; but 1 month later, logarithmic transformation of hs-CRP level was significantly lower in the niacin group (0.43 ± 0.39 to 0.83 ± 0.91, p = 0.04). HDL-C level was significantly increased in the niacin group during follow-up. Drug related side effects were seen in 7 patients in the niacin group but no patients discontinued niacin. Conclusions Our findings demonstrate that lower dose extended release niacin can be used safely and decreases hs-CRP and lipid parameters successfully in NSTE-ACS patients. PMID:27122858

    Full Text Available Abstract Background: The GRACE Score was derived and validated from a cohort in which octogenarians and nonagenarians were poorly represented. Objective: To test the accuracy of the GRACE score in predicting in-hospital mortality of very elderly individuals with acute coronary syndromes (ACS. Methods: Prospective observational study conducted in the intensive coronary care unit of a tertiary center from September 2011 to August 2016. Patients consecutively admitted due to ACS were selected, and the very elderly group was defined by age ≥ 80 years. The GRACE Score was based on admission data and its accuracy was tested regarding prediction of in-hospital death. Statistical significance was defined by p value < 0,05. Results: A total of 994 individuals was studied, 57% male, 77% with non-ST elevation myocardial infarction and 173 (17% very elderly patients. The mean age of the sample was 65 ± 13 years, and the mean age of very elderly patients subgroup was 85 ± 3.7 years. The C-statistics of the GRACE Score in very elderly patients was 0.86 (95% CI = 0.78 - 0.93, with no difference when compared to the value for younger individuals 0.83 (95% CI = 0.75 - 0.91, with p = 0.69. The calibration of the score in very elderly patients was described by χ2 test of Hosmer-Lemeshow = 2.2 (p = 0.98, while the remaining patients presented χ2 = 9.0 (p = 0.35. Logistic regression analysis for death prediction did not show interaction between GRACE Score and variable of very elderly patients (p = 0.25. Conclusion: The GRACE Score in very elderly patients is accurate in predicting in-hospital ACS mortality, similarly to younger patients.

    Full Text Available Inflammation can be activated as a defensive response by the attack of acute coronary syndrome (ACS for ischemic tissue injury. The aim of the present study was to investigate the impact of ACS-activated inflammation on adipokine imbalance and the effects of statins on the crosstalk between inflammation and adipokine imbalance during ACS. In this study, 586 subjects were categorized into: (1 control group; (2 SA (stable angina group; and (3 ACS group. Circulating levels of hs-CRP, adiponectin and resistin were measured by ELISA. Furthermore, forty C57BL/6 mice were randomized into: sham, AMI, low-statin (atorvastatin, 2 mg/kg/day and high-statin (atorvastatin, 20 mg/kg/day group. After 3 weeks, AMI models were established by surgical coronary artery ligation. Circulating levels and adipose expressions of adiponectin and resistin were assessed in animals. Besides, we investigate the effects of atorvastatin on ox-LDL-induced adipokine imbalance in vitro. As a result, we found that ACS patients had higher hs-CRP and resistin levels and lower adiponectin levels. Our correlation analysis demonstrated hs-CRP concentrations were positively correlated with resistin but negatively with adiponectin levels in humans. Our animal findings indicated higher circulating hs-CRP and resistin levels and lower adiponectin levels in AMI mice. Atorvastatin pre-treatment dose-dependently decreased hs-CRP and resistin levels but increased adiponectin levels in mice. The consistent findings were observed about the adipose expressions of resistin and adiponectin in mice. In study in vitro, ox-LDL increased cellular resistin expressions and otherwise for adiponectin expressions, which dose-dependently reversed by the addition of atorvastatin. Therefore, our study indicates that the ACS attack activates inflammation leading to adipokine imbalance that can be ameliorated by anti-inflammation of atorvastatin.

    BACKGROUND & HYPOTHESIS: Data on the clinical characteristics and outcome of patients presenting with acute coronary syndrome (ACS) according to their marital status is not clear. A total of 5334 patients presenting with ACS in 65 hospitals in 6 Middle East countries in the 2nd Gulf Registry of Acute Coronary Events (Gulf RACE-2) were studied according to their marital status (5024 married, 100 single, and 210 widowed patients). When compared to married patients, widowed patients were older and more likely to be female. Widowed patients were more likely to have diabetes mellitus, hypertension, history of heart failure, and peripheral vascular disease and were less likely to be tobacco users when compared to the other groups. Widowed patients were also more likely to present with atypical symptoms and have advanced Killip class. Widowed patients were more likely to present with non-ST-elevation myocardial infarction (NSTEMI) when compared to the other 2 groups. Widowed patients were more likely to have heart failure (P = 0.001), cardiogenic shock (P = 0.001), and major bleeding (P = 0.002) when compared to the other groups. No statistically significant difference was observed in regard to duration of hospital stay, door to needle time in STEMI patients, or cardiac arrhythmias between the various groups. Widowed patients had higher in-hospital, 30-day, and 1-year mortality rates (P = 0.001). Marital status was an independent predictor for in-hospital mortality. Widowed marital status was associated with worse cardiovascular risk profile, and worse in-hospital and 1-year outcome. Future work should be focused on whether the provision of psychosocial support will result in improved outcomes among this high-risk group. © 2012 Wiley Periodicals, Inc.

    Full Text Available   Abstract INTRODUCTION: Although coronary artery disease (CAD becomes symptomatic late in life, early identification and modification of risk factors may reduce its future incidence. methods: In this cross-sectional study, 108 subjects aged 6-18 years were randomly selected from among children of patients who underwent coronary angiography at Chamran Heart Center, Isfahan, Iran. The parents were assigned to two groups according to the presence or not of coronary stenosis in angiography. Each group was divided into two subgroups, with or without the metabolic syndrome. All of the subjects were aged below 55 years. In addition to anthropometric measurements, blood pressure, fasting serum glucose, and insulin level were measured and lipid profile was assessed in the children of the patients. The data were analyzed with SPSS using independent t-test, Kruskal-Wallis, chi-square and standard linear multiple regression tests. results: In the group with stenosis in coronary angiography, the prevalence of the metabolic syndrome components was significantly higher in children of parents with the metabolic syndrome than in the other group (24 vs. 18; P=0.003. In the group without stenosis in coronary angiography, the children of parents with the metabolic syndrome had higher triglyceride (TG levels and lower levels of high-density lipoprotein (HDL cholesterol, low-density lipoprotein (LDL cholesterol, total cholesterol, and fasting blood glucose. CONCLUSIONS: Our study emphasizes the importance of primordial and primary prevention of cardiovascular disease, especially in children of families with high risk of premature atherosclerosis.     Keywords: Metabolic syndrome, familial aggregation, cardiovascular disease.

    The natriuretic hormones are a family of vasoactive peptides that can be measured circulating in the blood. Because they serve as markers of hemodynamic stress, the major focus of the use of natriuretic peptide levels [predominantly B-type natriuretic peptide (BNP) and N-terminal (NT)-pro-BNP] has been as an aid to the clinical diagnosis and management of congestive heart failure (CHF). Recently, however, the measurement of natriuretic peptides in the acute coronary syndromes (ACS) has been shown to provide information complementary to traditional biomarkers (of necrosis) such as cardiac troponins and creatine kinase (CK). Studies in several types of acute coronary syndromes [ST-segment elevation myocardial infarction (STEMI), non-ST elevation MI (NSTEMI) and unstable angina (UA)] have shown that elevated levels of natriuretic peptides are independently associated with adverse outcomes, particularly mortality. Additional information is obtained from the use natriuretic peptides in combination with other markers of risk including biomarkers of necrosis and inflammation. This review will summarize the scientific rationale and clinical evidence supporting measurement of natriuretic peptides for risk stratification in acute coronary syndromes. Future research is needed to identify therapies of particular benefit for patients with ACS and natriuretic peptide elevation.

    The prognostic significance of prior heart failure in acute coronary syndromes has not been well studied. Accordingly, we evaluated the baseline characteristics, management patterns and clinical outcomes in patients with acute coronary syndromes who had prior heart failure. The study population consisted of acute coronary syndrome patients in the Global Registry of Acute Coronary Events, expanded Global Registry of Acute Coronary Events and Canadian Registry of Acute Coronary Events between 1999 and 2008. Of the 13,937 eligible patients (mean age 66±13 years, 33% female and 28.3% with ST-elevation myocardial infarction), 1498 (10.7%) patients had a history of heart failure. Those with prior heart failure tended to be older, female and had lower systolic blood pressure, higher Killip class and creatinine on presentation. Prior heart failure was also associated with significantly worse left ventricular systolic function and lower rates of cardiac catheterization and coronary revascularization. The group with previous heart failure had significantly higher rates of acute decompensated heart failure, cardiogenic shock, myocardial (re)infarction and mortality in hospital. In multivariable analysis, prior heart failure remained an independent predictor of in-hospital mortality (odds ratio 1.48, 95% confidence interval 1.08-2.03, p=0.015). Prior heart failure was associated with high risk features on presentation and adverse outcomes including higher adjusted in-hospital mortality in acute coronary syndrome patients. However, acute coronary syndrome patients with prior heart failure were less likely to receive evidence-based therapies, suggesting potential opportunities to target more intensive treatment to improve their outcome. © The European Society of Cardiology 2015.

    Full Text Available Background: Inflammation has been proposed as a contributor to different stages in the pathogenesis of Coronary Heart Disease (CHD. High sensitive C-Reactive Protein (hs-CRP, an acute-phase plasma protein synthesized by the liver, is the most extensively studied systemic marker of inflammation. Elevated hsCRP concentrations early in Acute Coronary Syndrome (ACS, prior to the tissue necrosis, may be a surrogate marker for cardiovascular co-morbidities. The cardiac marker enzymes Creatine Kinase myocardial bound (CK-MB, Aspartate Aminotransferase (AST and lactate dehydrogenase (LDH have been known to be increased in coronary artery diseases. Objective: The aim of the study was to measure hs-CRP levels and other cardiac marker enzymes in ACS patients and to compare the levels of hs-CRP with other cardiac marker enzymes between ST Elevation Myocardial Infarction (STEMI and Non-ST Elevation Myocardial Infarction (NSTEMI patients. Material and Methods: The study group consisted of 207 consecutive patients admitted to Sri Siddhartha Medical College Hospital within the first 6 hours from the onset of chest pain. Patients were diagnosed as Unstable Angina (UA, (n=84; STEMI (n=63 and NSTEMI (n=60. ACS patients were compared with 211 healthy age and sex matched controls. Hs-CRP, CK-MB, AST and LDH levels were measured by standard methods in both groups at baseline and forcases at 36-48 hours i.e. Peak levels. Results: ACS patients had significantly (p<0.05 higher levels of hs-CRP, CKMB, AST and LDH in comparison to controls at baseline. Hs-CRP, CK-MB, AST and LDH levels were significantly higher in STEMI patients compared to NSTEMI patients (p<0.05 at baseline. There was a significant difference regarding peak hs-CRP levels between the two groups, as STEMI patients had significantly higher peak hs-CRP levels compared to NSTEMI patients (p<0.05. Conclusion: STEMI patients have significantly higher peak hsCRP levels compared to NSTEMI patients. These data

    The optimal time-point of the initiation of P2Y12 antagonist therapy in patients with non-ST elevation acute coronary syndromes (NTSE-ACS) is still a matter of debate. European guidelines recommend P2Y12 as soon as possible after first medical contact. However, the only trial which compared the two...... strategies did not demonstrate any benefit of pre-treatment with prasugrel before angiography compared to starting therapy after angiography and just prior to percutaneous coronary intervention (PCI).

    Some studies reported a significant association between polycystic ovary syndrome (PCOS) and risk of cardiovascular disease (CVD). However, the results are controversial. A systematic search was conducted in the PubMed, Science Direct, EMBASE, and Cochrane Library databases. Five case-control studies and 5 cohort studies were selected, involving a total of 104392 subjects in this meta-analysis. PCOS was significantly associated with the increased risk of CVD (OR = 1.30; 95% CI 1.09 - 1.56; P = 0.004). In the subgroup analysis of study design, both case-control studies and prospective cohort studies showed significant results (OR = 1.79; 95% CI 1.16 - 2.77; P = 0.009; OR = 1.20; 95% CI 1.06 - 1.37; P = 0.005), while retrospective cohort studies did not show positive result (OR = 0.91; 95% CI 0.60 - 1.40; P = 0.68). In a further stratified analysis by type of CVD, a significant association was found between PCOS and coronary heart disease (CHD) (OR = 1.44; 95% CI 1.13 - 1.84; P = 0.004). However, no significant association was observed between PCOS and myocardial infarction (MI) (OR = 1.01; 95% CI 0.68 - 1.51; P = 0.95). In conclusion, this meta-analysis suggested that PCOS is significantly associated with increased CHD risk.

    It is well established that high on-treatment platelet reactivity to adenosine diphosphate during clopidogrel therapy is an independent risk factor for ischemic event occurrences in a postpercutaneous coronary intervention patients. However, the precise role of platelet function testing remains debated. Platelet function testing to ensure optimal platelet inhibition has been recommended by some authorities to improve outcomes in patients treated with clopidogrel. Recent prospective, randomized trials of personalized antiplatelet therapy have failed to demonstrate a benefit of platelet function testing in improving outcomes. In this review article, we discuss the mechanisms responsible for clopidogrel nonreponsiveness, recent trials of platelet function testing, and other new developments in the field of personalized antiplatelet therapy.

Methods: A retrospective analysis was conducted using the Medical Expenditure Panel Survey from 1998 to 2009. Four mutually exclusive cohorts were evaluated: ACS only, ACS with atrial fibrillation (AF, ACS with heart failure (HF, and ACS with both conditions. Direct costs were calculated for all-cause and cardiovascular-related health care resource utilization. Indirect costs were determined from productivity losses from missed days of work. Regression analysis was developed for each outcome controlling for age, US census region, insurance coverage, sex, race, ethnicity, education attainment, family income, and comorbidity burden. A negative binomial regression model was used for health care utilization variables. A Tobit model was utilized for health care costs and productivity loss variables. Results: Total health care costs were greatest for those with ACS and both AF and HF ($38,484±5,191 followed by ACS with HF ($32,871±2,853, ACS with AF ($25,192±2,253, and ACS only ($17,954±563. Compared with the ACS only cohort, the mean all-cause adjusted health care costs associated with ACS with AF, ACS with HF, and ACS with AF and HF were $5,073 (95% confidence interval [CI] 719–9,427, $11,297 (95% CI 5,610–16,985, and $15,761 (95% CI 4,784–26,738 higher, respectively.

    Aldosterone may have adverse effects in the myocardium and vasculature. Treatment with an aldosterone antagonist reduces cardiovascular risk in patients with acute myocardial infarction complicated by heart failure (HF) and left ventricular systolic dysfunction. However, most patients with acute coronary syndrome do not have advanced HF. Among such patients, it is unknown whether aldosterone predicts cardiovascular risk. To address this question, we examined data from the dal-OUTCOMES trial that compared the cholesteryl ester transfer protein inhibitor dalcetrapib with placebo, beginning 4 to 12 weeks after an index acute coronary syndrome. Patients with New York Heart Association class II (with LVEF coronary heart disease death, nonfatal myocardial infarction, stroke, hospitalization for unstable angina, or resuscitated cardiac arrest. Hospitalization for HF was a secondary endpoint. Over a median follow-up of 37 months, the primary outcome occurred in 366 patients (9.0%), and hospitalization for HF occurred in 72 patients (1.8%). There was no association between aldosterone and either the time to first occurrence of a primary outcome (hazard ratio for doubling of aldosterone 0.92, 95% confidence interval 0.78-1.09, P=0.34) or hospitalization for HF (hazard ratio 1.38, 95% CI 0.96-1.99, P=0.08) in Cox regression models adjusted for covariates. In patients with recent acute coronary syndrome but without advanced HF, aldosterone does not predict major cardiovascular events. URL: http://www.clinicaltrials.gov.

    CYP2C19 is a major isoform of cytochrome P450 that metabolizes a number of drugs and is involved in the glucocorticoids synthesis. CYP2C19 polymorphisms have been associated with the genetic risk for type 2 diabetes. Five hundred and three patients with an acute coronary event were studied to assess the association between the CYP2C19 activity (CYP2C19*2, CYP2C19*3 and CYP2C19*17 variants) and the type of acute coronary syndrome, cardiovascular risk factors (arterial systemic hypertension, diabetes mellitus, dyslipidemia and smoking), analytical parameters and the extent and severity of coronary atherosclerosis. Genotype distribution in our series was similar to that expected in the Caucasian population. Among the traditional cardiovascular risk factors, very poor metabolizer patients (*2/*2, *3/*3 or *2/*3) had a greater tendency to present diabetes mellitus needing insuline (P=.067). Conversely, when we compared very poor, poor and normal metabolizers vs. rapid and ultrarapid metabolizers we found significant differences in those diabetic patients under insulin treatment (64 patients [18%] vs. 17 patients [11%]; P=.032). On the contrary, analytical parameters, systemic arterial hypertension, dyslipidemia, smoking or the personal/family history of coronary artery disease did not reach statistical significance regardless of CYP2C19 activity. Similarly, the number and the type of coronary disease (thrombotic, fibrotic or both) did not differ between patients with different CYP2C19 enzyme activity. Patients with an acute coronary event and a very poor, poor and normal CYP2C19 metabolizer genotype have a higher prevalence of diabetes mellitus needing insuline than patients with the rapid and ultrarapid metabolizers CPY2C19 genotype.

    Thrombotic events in antiphospholipid syndrome (APS) involve venous and arterial circulation with the possible involvement of coronary or pulmonary microcirculation. To evaluate the influence of antiphospholipid antibodies (aPL) and on myocardial ischaemia assessed by single-photon emission computerized tomography (SPECT), coronary atherosclerosis assessed by multidetector computerized tomography (MDCT) and pulmonary pressure assessed by transthoracic echocardiography (TTE) in patients with primary antiphospholipid syndrome (PAPS). TTE, SPECT (Tc 99m sestamibi) and MDCT-based coronary calcium scoring were performed in 26 consecutive PAPS patients (20 females, 6 males, aged 20-61, mean 39.7) without any signs of other autoimmunological disease and without clinical symptoms of heart disease. Out of 26 patients, TEE showed normal left and right ventricle function in 25 (96.2%) and elevated (≥ 30 mm Hg) right ventricle systolic pressure in 7 (26.9%) patients. SPECT revealed myocardial perfusion defects in 15 (57.7%) patients: exercise-induced in 6 (23.1%) and persistent in 11 (42.3%). MDCT revealed coronary calcifications in 4 (15.4%) patients. The number of plaques ranged from 1 to 11 (median 2), volume 3-201.7 mm³ (median 7), calcium scores 1.3-202.6 (median 5.7). In the group with perfusion defects or coronary calcifications (n = 15), all the patients showed elevated aCL IgG. In most of the relatively young APS patients, without any symptoms of ischemic heart disease, SPECT showed myocardial perfusion defects, and coronary calcifications in 1/6 of them. Right ventricle systolic pressure was elevated in 1/4 of APS patients. These pathologies, well known as cardiovascular risk markers, were associated with elevated levels of the IgG class of both anti-cardiolipin and antiB2 GPI antibodies. Thus, in a high percentage of APS patients, clinically silent myocardial ischaemia, pulmonary pressure elevation and coronary atherosclerosis are present and related to the

    Full Text Available Background: Inflammation plays a major role in the development and progression of atherosclerosis and coronary artery disease (CAD. Inflammation markers, including white blood cell (WBC count, C-reactive protein (CRP and interleukin-6 (IL-6, are widely used for cardiovascular risk prediction. The aim of the study was to establish factors associated with WBC, CRP and IL-6 in patients with CAD. Two functional polymorphisms in genes encoding enzymes participating in adenosine metabolism were analyzed (C34T AMPD1, G22A ADA. Methods: Plasma concentrations of IL-6 were measured using high-sensitivity ELISA kits, and the nephelometric method was used for high-sensitivity CRP (hs-CRP measurement in 167 CAD patients. Results: Presence of metabolic syndrome (MS and its components, presence of heart failure, severity of CAD symptoms, severe past ventricular arrhythmia (sustained ventricular tachycardia [sVT] or ventricular fibrillation [VF], lower left ventricle ejection fraction, higher left ventricle mass index, higher end-diastolic volume and higher number of smoking pack-years were significantly associated with higher WBC, CRP and IL-6. Strong associations with arrhythmia were observed for IL-6 (median 3.90 vs 1.89 pg/mL, p<0.00001 and CRP concentration (6.32 vs 1.47 mg/L, p=0.00009, while MS was associated most strongly with IL-6. CRP and IL-6 were independent markers discriminating patients with sVT or VF. There were no associations between AMPD1 or ADA genotypes and inflammation markers. Conclusions: WBC, CRP and IL-6 are strongly associated with components of the metabolic syndrome. Their strong association with life-threatening ventricular arrhythmia emphasizes the proarrhythmic role of inflammation in the increased cardiovascular risk of CAD patients.

    To assess the association of leisure-time exercise and television (TV) viewing, a sedentary marker, with acute coronary syndrome (ACS) in Albania, a transitional country in Southeast Europe. A population-based case-control study was conducted among Tirana residents in 2003-2006. Information on leisure-time exercise (transformed into kilocalories of energy expenditure) and daily hours of TV viewing was obtained by interviewer-administered questionnaire. 460 non-fatal ACS patients (368 men, 92 women) and 628 coronary heart disease-free controls (413 men, 215 women) were studied. Adjusted for socio-demographic characteristics, conventional coronary risk factors and leisure-time exercise, TV viewing was associated with ACS in women (OR=1.66, 95%CI=1.12-2.46 per hour/day viewing), but not in men (OR=0.93, 95%CI=0.81-1.07; P for sex-interaction=0.02). A low level of leisure-time exercise (adjusted also for TV viewing) was associated with ACS similarly in men and women (pooled sexes OR=2.03, 95%CI=1.29-3.22 for bottom vs top tertile of energy expenditure). Leisure-time inactivity is confirmed as an important risk factor for ACS also in Southeastern Europe. TV viewing may be an informative coronary risk marker in transitional societies, especially in women.

    Acute coronary syndromes (ACS) may precipitate up to a third of acute heart failure (AHF) cases. We assessed the characteristics, initial management, and survival of AHF patients with (ACS-AHF) and without (nACS-AHF) concomitant ACS. Data from 620 AHF patients were analyzed in a prospective multicenter study. The ACS-AHF patients (32%) more often presented with de novo AHF (61% vs. 43%; P coronary procedures (angiography, percutaneous coronary intervention, coronary artery bypass graft surgery), were more frequent in ACS-AHF (P < .001 for all). Although 30-day mortality was significantly higher for ACS-AHF (13% vs. 8%; P = .03), survival in the 2 groups at 5 years was similar. Overall, ACS was an independent predictor of 30-day mortality (adjusted odds ratio 2.0, 95% confidence interval 1.07-3.79; P = .03). Whereas medical history and the manifestation and initial treatment of AHF between ACS-AHF and nACS-AHF patients differ, long-term survival is similar. ACS is, however, independently associated with increased short-term mortality. Copyright © 2014 Elsevier Inc. All rights reserved.

    2015-01-01

    INTRODUCTION: Among patients with acute chest pain, acute coronary syndrome (ACS) is seen only in a minority of the patients, which raises the question, whether it is possible to separate a group with a high risk of ACS for admission to a cardiac care unit (CCU) from those with a low risk who would...... be treated at an emergency department (ED). The aim of this study was to describe a risk stratification model for a Danish context. METHODS: This was a historic prospective cohort study of patients with suspicion of ACS. The patient was defined as a low-risk patient and admitted to the ED if: 1....... RESULTS: We included a total of 488 patients with suspicion of ACS, 50% of whom were low-risk patients. 17% had a verified ACS; 10% of those in the low-risk group and 24% of those in the high-risk group (p = 0.0001). Among the verified ACS cases, 71% went primarily to the CCU. The odds ratio for an ACS...

    Several reports have suggested that nitrates limit acute ischaemic damage by a mechanism similar to preconditioning. This study aims to evaluate the effect of chronic oral nitrates on the clinical presentation and short-term outcomes of patients admitted with acute coronary syndrome (ACS). A retrospective cohort study was conducted in patients with ACS admitted to 62 acute care units from 2010 to 2011. A propensity score-matched samples analysis was performed. We analysed 3171 consecutive patients, of whom 298 (9.4%) were chronically treated with nitrates. Patients previously treated with nitrates had higher comorbidity and disease severity at admission, lower prevalence of ACS with ST elevation, lower troponin elevation, higher prevalence of initial Killip class 2-4 and higher hospital mortality. The propensity score-matched analysis confirmed that previous use of nitrates is independently associated with a lower prevalence of ST-elevation ACS [odds ratio (OR) 0.53, 95% confidence interval (CI) 0.36-0.78; P = 0.0014] and a lower troponin elevation (OR 0.61, 95% CI 0.41-0.92) but not with Killip class on admission (OR 1.18, 95% CI 0.83-1.67, P = 0.3697) or mortality (OR 0.71, 95% CI 0.37-1.38, P = 0.3196). The results support the hypothesis that nitrates have a protective effect on acute ischaemic injury.

    Full Text Available Background. To differentiate acute coronary syndrome (ACS from other causes in patients presenting with chest pain at the emergency department (ED is crucial and can be performed by the nurse triage. We evaluated the effectiveness of the ED nurse triage for ACS of the tertiary care hospital. Methods. We retrospectively enrolled consecutive patients who were identified as ACS at risk patients by the ED nurse triage. Patients were categorized as ACS and non-ACS group by the final diagnosis. Multivariate logistic analysis was used to predict factors associated with ACS. An online model predictive of ACS for the ED nurse triage was constructed. Results. There were 175 patients who met the study criteria. Of those, 28 patients (16.0% were diagnosed with ACS. Patients with diabetes, patients with previous history of CAD, and those who had at least one character of ACS chest pain were independently associated with having ACS by multivariate logistic regression. The adjusted odds ratios (95% confidence interval were 4.220 (1.445, 12.327, 3.333 (1.040, 10.684, and 12.539 (3.876, 40.567, respectively. Conclusions. The effectiveness of the ED nurse triage for ACS was 16%. The online tool is available for the ED triage nurse to evaluate risk of ACS in individuals.

    In spite of robust knowledge about underlying ischemic myocardial damage, acute coronary syndromes (ACS) with culprit-free angiograms raise diagnostic concerns. The present study aimed to evaluate the additional value of cardiac magnetic resonance (CMR) over commonly available non-CMR standard tests, for the differentiation of myocardial injury in patients with ACS and non-obstructed coronary arteries. Patients with ACS, elevated hs-TnT, and a culprit-free angiogram were prospectively enrolled into the study between January 2009 and July 2013. After initial evaluation with standard tests (ECG, echocardiography, hs-TnT) and provisional exclusion of acute myocardial infarction (AMI) in coronary angiogram, patients were referred for CMR with the suspicion of myocarditis or Takotsubo cardiomyopathy (TTC). According to the result of CMR, patients were reclassified as having myocarditis, AMI, TTC, or non-injured myocardium as assessed by late gadolinium enhancement. Out of 5110 patients admitted with ACS, 75 had normal coronary angiograms and entered the study; 69 of them (92%) were suspected for myocarditis and 6 (8%) for TTC. After CMR, 49 patients were finally diagnosed with myocarditis (65%), 3 with TTC (4%), 7 with AMI (9%), and 16 (21%) with non-injured myocardium. The provisional diagnosis was changed or excluded in 23 patients (31%), with a 9% rate of unrecognized AMI. The study results suggest that the evaluation of patients with ACS and culprit-free angiogram should be complemented by a CMR examination, if available, because the initial work-up with non-CMR tests leads to a significant proportion of misdiagnosed AMI.

    Full Text Available Objective: Translation of evidence into practice by health systems can be slow and incomplete and may disproportionately impact disadvantaged populations. Coronary heart disease is the leading cause of death among Aboriginal Australians. Timely access to effective medical care for acute coronary syndrome substantially improves survival. A quality-of-care audit conducted at a regional Western Australian hospital in 2011–2012 compared the Emergency Department management of Aboriginal and non-Aboriginal acute coronary syndrome patients. This audit is used as a case study of translating knowledge processes in order to identify the factors that support equity-oriented knowledge translation. Methods: In-depth interviews were conducted with a purposive sample of the audit team and further key stakeholders with interest/experience in knowledge translation in the context of Aboriginal health. Interviews were analysed for alignment of the knowledge translation process with the thematic steps outlined in Tugwell’s cascade for equity-oriented knowledge translation framework. Results: In preparing the audit, groundwork helped shape management support to ensure receptivity to targeting Aboriginal cardiovascular outcomes. Reporting of audit findings and resulting advocacy were undertaken by the audit team with awareness of the institutional hierarchy, appropriate timing, personal relationships and recognising the importance of tailoring messages to specific audiences. These strategies were also acknowledged as important in the key stakeholder interviews. A follow-up audit documented a general improvement in treatment guideline adherence and a reduction in treatment inequalities for Aboriginal presentations. Conclusion: As well as identifying outcomes such as practice changes, a useful evaluation increases understanding of why and how an intervention worked. Case studies such as this enrich our understanding of the complex human factors, including

    Full Text Available Objective. To describe a single case of Systemic Capillary Leak Syndrome (SCLS with a rare complication of compartment syndrome. Patient. Our patient is a 57-year-old male, referred to our hospital due to polycythemia (hemoglobin (Hgb of 220 g/L, hypotension, acute renal failure, and bilateral calf pain. Measurements and Main Results. The patient required bilateral forearm, thigh, and calf fasciotomies during his ICU stay and continuous renal replacement therapy was instituted following onset of acute renal failure and oliguria. Ongoing hemodynamic (Norepinephrine and Milrinone infusion and respiratory (ventilator support in the ICU was provided until resolution of intravascular fluid extravasation. Conclusions. SCLS is an extremely rare disorder characterized by unexplained episodic capillary hyperpermeability, which causes shift of volume and protein from the intravascular space to the interstitial space. Patients present with significant hypotension, hemoconcentration, hypovolemia, and oliguria. Severe edema results from leakage of fluid and proteins into tissue. The most important part of treatment is maintaining stable hemodynamics, ruling out other causes of shock and diligent monitoring for complications. Awareness of the clinical syndrome with the rare complication of compartment syndrome may help guide investigations and diagnoses of these critically ill patients.

    We investigated the relation between overall atheroma burden and clinical events in the Providing Regional Observations to Study Predictors of Events in the Coronary Tree (PROSPECT) study. In PROSPECT, 660 patients (3,229 nonculprit lesions with a plaque burden ≥ 40% and complete intravascular ultrasound data) were divided into tertiles according to baseline percent atheroma volume (PAV: total plaque/vessel volume). Patients were followed for 3.4 years (median); major adverse cardiac events (MACE: death from cardiac causes, cardiac arrest, myocardial infarction, or rehospitalization because of unstable or progressive angina) were adjudicated to either culprit or nonculprit lesions. Compared with patients in low or intermediate PAV tertiles, patients in the high PAV tertile had the greatest prevalence of plaque rupture and radiofrequency thin-cap fibroatheroma (VH-TCFA) and the highest percentage of necrotic core volume; they were also more likely to have high-risk lesion characteristics: ≥ 1 lesion with minimal luminal area ≤ 4 mm(2), plaque burden >70%, and/or VH-TCFA. Three-year cumulative nonculprit lesion-related MACE was greater in the intermediate and high tertiles than in the low tertile (6.3% vs 14.7% vs 15.1%, low vs intermediate vs high tertiles, p = 0.009). On Cox multivariable analysis, insulin-dependent diabetes (hazard ratio [HR] 3.98, p = 0.002), PAV (HR 1.06, p = 0.03), and the presence of ≥1 VH-TCFA (HR 1.80, p = 0.02) were independent predictors of nonculprit MACE. In conclusion, increasing baseline overall atheroma burden was associated with more advanced, complex, and vulnerable intravascular ultrasound lesion morphology and independently predicted nonculprit lesion-related MACE in patients with acute coronary syndromes after successful culprit lesion intervention.

    Full Text Available We present a case of a 34-year-old male who presented to the emergency ward with fever and abdominal pain. The diagnosis of Takayasu’s arteritis and also antiphospholipid syndrome was made during an imaging workup of deep-vein thrombosis. A spontaneous coronary artery dissection was revealed in coronary CT angiography requested for chest pain and dyspnea. The patient was treated medically and discharged on close followup. The concurrence of spontaneous coronary artery dissection with antiphospholipid syndrome and Takayasu’s arteritis has not been reported in the previous literature. The possibility of a spontaneous coronary artery dissection should be considered in patients presenting with both diseases.

    2015-01-01

    Full Text Available The receptor of advanced glycation end products (RAGE and its ligands are linked to the pathogenesis of coronary artery disease (CAD, and circulating soluble receptor of advanced glycation end products (sRAGE, reflecting the RAGE activity, is suggested as a potential biomarker. Elevated sRAGE levels are reported in relation to acute ischemia and this review focuses on the role of sRAGE as a biomarker for the acute coronary syndrome (ACS. The current studies demonstrated that sRAGE levels are elevated in relation to ACS, however during a very narrow time period, indicating that the time of sampling needs attention. Interestingly, activation of RAGE may influence the pathogenesis and reflection in sRAGE levels in acute and stable CAD differently.

    Full Text Available The basic anthropometric data describing a person in the broadest context are body weight and height, two of the most frequently analyzed somatometric parameters. The same is true I in relation to clinical patients. The aim of the present study was to compare the self-reported and actual body weight, height and BMI in patients suffering from coronary artery disease and undergoing cardiac rehabilitation. The study sample consisted of 100 patients treated for coronary artery disease. The patients were asked to state their body weight and height. At the same time a three-person study team took measurements, which were later the basis for verification and objective assessment of the data provided by the patients. Statistical analysis was performed with Statistics 11.0 PL software. The analysis of mean results for the assessed group of patients has shown the presence of statistically significant differences between declared and actual data. The differences were observed for both male and female study population. It has been proven that the subjects declare greater body height (mean value 1.697 m vs. 1.666 m and lower body weight (80.643 kg vs. 82.051 kg. Based on the data from surveys and direct measurements, the body mass index for the self-reported and actual data was calculated. A comparison of these values has shown considerable statistically significant differences. The differences between declared and actual data point to highly subjective self-assessment, which disqualifies the declared data in the context of monitoring of treatment and rehabilitation processes. The authors believe that actual data should be used in direct trial examination of patients suffering from coronary artery disease who presented with acute coronary syndrome.

    2015-12-01

    Full Text Available The aim of this study was to evaluate the possibility of incorrect assessment of mortality risk factors in a group of patients affected by acute coronary syndrome, due to the lack of hazard proportionality in the Cox regression model. One hundred and fifty consecutive patients with acute coronary syndrome (ACS and no age limit were enrolled. Univariable and multivariable Cox proportional hazard analyses were performed. The proportional hazard assumptions were verified using Schoenfeld residuals, χ2 test and rank correlation coefficient t between residuals and time. In the total group of 150 patients, 33 (22.0% deaths from any cause were registered in the follow-up time period of 64 months. The non-survivors were significantly older and had increased prevalence of diabetes and erythrocyturia, longer history of coronary artery disease, higher concentrations of serum creatinine, cystatin C, uric acid, glucose, C-reactive protein (CRP, homocysteine and B-type natriuretic peptide (NT-proBNP, and lower concentrations of serum sodium. No significant differences in echocardiography parameters were observed between groups. The following factors were risk of death factors and fulfilled the proportional hazard assumption in the univariable model: smoking, occurrence of diabetes and anaemia, duration of coronary artery disease, and abnormal serum concentrations of uric acid, sodium, homocysteine, cystatin C and NT-proBNP, while in the multivariable model, the risk of death factors were: smoking and elevated concentrations of homocysteine and NT-proBNP. The study has demonstrated that violation of the proportional hazard assumption in the Cox regression model may lead to creating a false model that does not include only time-independent predictive factors.

    To determine the usefulness of myeloperoxidase in discriminating between patients with acute coronary syndrome and patients with chest pain by other causes. The study included all patients over 18 years of age who come consecutively to the emergency department from September 2015 to December 2015 with chest pain of non-traumatic origin. The initial patient evaluation was performed according to the study protocol for patients with suspected acute coronary syndrome (ACS) in our Emergency Department. This included the serial measurement of troponin, and in this case myeloperoxidase, with serialization on admission and at 6h. For the determination of myeloperoxidase (MPO), a single step sandwich enzyme immunoassay by Siemens, automated on a Dimension analyser, was used. Statistically significant differences were observed in the concentration of myeloperoxidase at time 0 among patients diagnosed with ACS: 505 (413)pmol/L, and non-ACS patients: 388 (195)pmol/L (p<.001), as well as at 6h (p<.001). An area under the curve ROC of 0.824 was obtained at 6h for ACS patients, with a confidence interval of 95% from 0.715 to 0.933 and a level of significance of p<.001. Statistically significant differences were also found in the concentration of myeloperoxidase at time 0 and at 6h among patients with ACS and patients with heart disease other than coronary artery disease. The concentration of MPO helps to differentiate between ACS and non-ACS patients, as well as between ACS patients and patients with heart diseases other than coronary artery disease.

    Coronary artery bifurcation disease of saphenous venous graft (SVG) is extremely rare. SVG disease remains a challenging lesion to treat because of increased morbidity and mortality with repeated coronary artery bypass graft surgery (CABG), high rates of periprocedural complications, and in-stent restenosis or occlusion requiring repeat revascularization with percutaneous coronary intervention. Herein, we present the first reported case of using the "DK crush" technique to treat an inverted Y-shaped SVG bifurcation disease in a patient with a prior CABG and new-onset acute coronary syndrome. Arising from our treatment, favorable immediate and mid-term angiographic and clinical outcomes were obtained. Coronary artery bypass surgery (CABG); "DK crush" technique; Saphenous venous graft (SVG).

    Patients with angina-like chest pain without evidence of epicardial coronary artery disease or coronary arterial vasospasm are becoming increasingly recognized. These are often related to noncardiac causes including esophageal, musculoskeletal, and hyperventilatory or panic states. However, recently a subgroup of such patients are being recognized as having true myocardial ischemia and chest pain on the basis of diminished coronary microvascular vasodilatory reserve (microvascular ischemia or Syndrome X). The authors describe such a patient who was found to have replication of anginal pain associated with a reversible ischemic defect on thallium 201 imaging during atrial pacing, suggesting ischemia in this myocardial segment. Resolution of angina and ST segment electrocardiographic changes of ischemia occurred with cessation of pacing. We believe this is the first report of a patient with this form of myocardial ischemia diagnosed by this method and should be considered in patients with anginal chest pain after significant coronary artery disease and coronary vasospasm have been excluded

A total of 7226 patients from a randomized trial, testing the effect on cardiovascular outcomes of the dual peroxisome proliferator-activated receptor agonist aleglitazar in patients with type 2 diabetes mellitus and recent acute coronary syndrome (AleCardio trial), were analysed. Median follow-up was 2 years. The independent mortality predictors were defined using Cox regression analysis. The predictive information provided by each variable was calculated as percent of total chi-square of the model. All-cause mortality was 4.0%, with cardiovascular death contributing for 73% of mortality. The mortality prediction model included N-terminal proB-type natriuretic peptide (adjusted hazard ratio = 1.68; 95% confidence interval = 1.51-1.88; 27% of prediction), lack of coronary revascularization (hazard ratio = 2.28; 95% confidence interval = 1.77-2.93; 18% of prediction), age (hazard ratio = 1.04; 95% confidence interval = 1.02-1.05; 15% of prediction), heart rate (hazard ratio = 1.02; 95% confidence interval = 1.01-1.03; 10% of prediction), glycated haemoglobin (hazard ratio = 1.11; 95% confidence interval = 1.03-1.19; 8% of prediction), haemoglobin (hazard ratio = 1.01; 95% confidence interval = 1.00-1.02; 8% of prediction), prior coronary artery bypass (hazard ratio = 1.61; 95% confidence interval = 1.11-2.32; 7% of prediction) and prior myocardial infarction (hazard ratio = 1.40; 95% confidence interval = 1.05-1.87; 6% of prediction). In patients with type 2 diabetes mellitus and recent acute coronary syndrome, mortality prediction is largely dominated by markers of cardiac, rather than metabolic, dysfunction.

    Full Text Available Coronary sinus anomalies are rare congenital defects which are usually coexistent with a persistent left superior vena cava and may be associated with cardiac arrhythmias. We report an unroofed coronary sinus without persistent left superior vena cava diagnosed during a catheter ablation procedure for Wolff-Parkinson-White syndrome. Diagnostic and therapeutic options and outcomes are discussed. This condition is of relevance to electrophysiologists performing catheter-based procedures, as well as cardiologists implanting coronary sinus pacing leads, who may encounter this anomaly in their practice.

    Posteroseptal accessory pathways are often associated with coronary sinus diverticula. These diverticula contain myocardial coats which serve as a bypass tract. We report a 54-year-old woman who underwent radiofrequency (RF) catheter ablation for Wolff-Parkinson-White (WPW) syndrome. The surface electrocardiography (ECG) demonstrated pre-excitation, indicating a posteroseptal accessory pathway. A catheter ablation via a transaortic approach failed to ablate the accessory pathway. Coronary sinus venography revealed the presence of a diverticulum near the ostium. An electrogram in the neck of the diverticulum showed the coronary sinus myocardial extension potential, which was successfully ablated by delivery of RF energy. PMID:19949625

    Full Text Available Background: Cardiovascular disease is the leading cause of mortality in the western world and its treatment should be optimized to decrease severe adverse events. Objective: To determine the effect of previous use of angiotensin-converting enzyme inhibitors on cardiac troponin I measurement in patients with acute coronary syndrome without ST-segment elevation and evaluate clinical outcomes at 180 days. Methods: Prospective, observational study, carried out in a tertiary center, in patients with acute coronary syndrome without ST-segment elevation. Clinical, electrocardiographic and laboratory variables were analyzed, with emphasis on previous use of angiotensin-converting enzyme inhibitors and cardiac troponin I. The Pearson chi-square tests (Pereira or Fisher's exact test (Armitage were used, as well as the non-parametric Mann-Whitney's test. Variables with significance levels of 0.5 ng / mL were high blood glucose at admission (p = 0.0034 and ST-segment depression ≥ 0.5 mm in one or more leads (p = 0.0016. The use of angiotensin-converting inhibitors prior to hospitalization was associated with troponin ≤ 0.5 ng / mL (p = 0.0482. The C-statistics for this model was 0.77. Conclusion: This study showed a correlation between prior use of angiotensin-converting enzyme inhibitors and reduction in the myocardial necrosis marker troponin I in patients admitted for acute coronary syndrome without ST-segment elevation. However, there are no data available yet to state that this reduction could lead to fewer severe clinical events such as death and re-infarction at 180 days.

    Objectives This study sought to determine if there is an association between bleed location and clinical outcomes in acute coronary syndromes (ACS) patients. Background The prognostic significance of bleeding location among ACS patients undergoing cardiac catheterization is not well known. Methods We analyzed in-hospital bleeding events among 9,978 patients randomized in the SYNERGY (Superior Yield of the New Strategy of Enoxaparin, Revascularization, and Glycoprotein IIb/IIIa Inhibitors) study. Bleeding events were categorized by location as access site, systemic, surgical, or superficial, and severity was graded using the GUSTO (Global Use of Strategies to Open Occluded Coronary Arteries) definition. We assessed the association of each bleeding location and severity with 6-month risk of death or myocardial infarction using a multicovariate-adjusted Cox proportional hazard model. Results A total of 4,900 bleeding events were identified among 3,694 ACS patients with in-hospital bleeding. Among 4,679 GUSTO mild/moderate bleeding events, only surgical and systemic bleeds were associated with an increased risk of 6-month death or myocardial infarction (adjusted hazard ratio [HR]: 2.52 [95% confidence interval (CI): 2.16 to 2.94, and 1.40 [95% CI: 1.16 to 1.69], respectively). Mild/moderate superficial and access-site bleeds were not associated with downstream risk (adjusted HR: 1.17 [95% CI: 0.97 to 1.40], and 0.96 [95% CI: 0.82 to 1.12], respectively). Among 221 GUSTO severe bleeds, surgical bleeds were associated with the highest risk (HR: 5.27 [95% CI: 3.80 to 7.29]), followed by systemic (HR: 4.48 [95% CI: 2.98 to 6.72]), and finally access-site bleeds (HR: 3.57 [95% CI: 2.35 to 5.40]). Conclusions Among ACS patients who develop in-hospital bleeding, systemic and surgical bleeding are associated with the highest risks of adverse outcomes regardless of bleeding severity. Although the most frequent among bleeds, GUSTO mild/moderate access-site bleeding is not

    Full Text Available Aortic dissection is a critical condition requiring immediate assessment and management. Clinical presentation is commonly associated with severe chest pain and high blood pressure. However, misdiagnosis is frequent because of various features. We presented a case of 51-year-old woman who complained of dyspnea for 3 d after she experienced back pain for one week. She was presented with severe respiration distress with impending respiration failure on arrival to our hospital. Her chest X-ray showed cardiomegaly with acute pulmonary edema. The laboratory data revealed elevated cardiac enzyme and electrocardiography demonstrated sinus tachycardia. She was hospitalized under the initial diagnosis of acute coronary syndrome. The patient remained hemodynamically stable, and experienced one episode of chest discomfort. After electrocardiography, she was found with bigeminy ventricular premature beats without ST-T change. Follow-up cardiac enzyme demonstrated progressive declined. Cardiac catheterization was performed on the third day of admission, and coronary angiography revealed large intimal flap on aortic root with bilateral coronary artery involvement. Surgical management was arranged after immediate chest computed tomography study.

    The aim of this study was to report the frequency, patient and lesion-related characteristics, and outcomes of subclinical, nonculprit plaque ruptures in the PROSPECT (Providing Regional Observations to Study Predictors of Events in the Coronary Tree) study. Plaque rupture and subsequent thrombosis is the most common cause of acute coronary syndrome (ACS). Secondary, subclinical, nonculprit plaque ruptures have been seen in both stable patients and patients with ACS; however, reports of the natural history of these secondary plaque ruptures are limited. After successful stenting in 697 patients with ACS, 3-vessel grayscale and intravascular ultrasound virtual histology (IVUS-VH) was performed in the proximal-mid segments of all 3 coronary arteries as part of a prospective multicenter study. Among 660 patients with complete IVUS data, 128 plaque ruptures were identified in 105 nonculprit lesions in 100 arteries from 93 patients (14.1%). Although the minimum lumen area (MLA) was similar, the plaque burden was significantly greater in nonculprit lesions with a plaque rupture compared with nonculprit lesions without a plaque rupture (66.0% [95% confidence interval: 64.5% to 67.4%] vs. 56.0% [95% confidence interval: 55.6% to 56.4%]; p PROSPECT]; NCT00180466).

    Few cases of Churg-Strauss syndrome (CSS) complicated by giant coronary aneurysms (CAs)have been reported thus far. We report a case of CSS in a 60-year-old man who underwent surgery for giant CAs, and was managed with anesthetics. The patient developed acute myocardial infarction, and was diagnosed with giant CAs in the right coronary artery (RCA, 11 cm) and circumflex artery (3 cm). The CA in RCA was communicating with the right ventricle. He had a history of pericardiectomy for pericarditis caused by the CSS and developed thrombocytopenia due to consumptive coagulopathy within the CAs. An operation, including ligation and excision of the CAs, and coronary artery bypass grafting was performed under general anesthesia and cardiopulmonary bypass. There was massive hemorrhage followed by hemodynamic instability while detaching the tight pericardial adhesion and fragile surface of the CAs. Massive transfusion was required along with inotropes administration and intraaortic balloon support. In this case, determination of the appropriate surgical timing was difficult because symptoms of the CSS became worse followed by rapid enlargement of the CAs, myocardial infarction, and thrombocytopenia. Steroids were administered for treating CSS, and the blood transfusion was sufficient. However, it was difficult to control the hemorrhage and maintain hemodynamic stability.

    Authors have found that the effect in the title (DEE) exists in cardiac CT images due to the contrasting agent used for percutaneous coronary intervention (PCI) done shortly after the onset of acute coronary syndrome (ACS). To confirm the finding, they compared images of the cardiac CT and blood flow single photon emission computed tomography (SPECT) obtained several days after ACS. The cardiac CT images of 17 patients (M 15, F 2; average age 63.6 y) with ACS were obtained 20-30 min after the successfully attained emergent enhanced PCI, with the 4-row multi detector low CT (MDCT) machine Aquilion (Toshiba) in synchronization to R-R interval for processing to multiplanar reconstructed (MPR) images. Thereafter (5.5 days in average), myocardial SPECT was conducted with 99m Tc-tetrofosmin (740 MBq), of which images were also processed to MPR ones. The CT and SPECT images were compared in coronary arterial territories assigned to 17 segments in the left ventricle and to 20 areas in the Bull's-eye Map. Findings due to DEE in the former CT images were confirmed well correspondent with the lesion found in the latter SPECT, indicating that DEE is a useful tool for evaluation of ACS severity. (R.T.)

    Full Text Available Background: Clinical major adverse cardiovascular event (MACE prediction of acute coronary syndrome (ACS is important for a number of applications including physician decision support, quality of care assessment, and efficient healthcare service delivery on ACS patients. Admission records, as typical media to contain clinical information of patients at the early stage of their hospitalizations, provide significant potential to be explored for MACE prediction in a proactive manner. Methods: We propose a hybrid approach for MACE prediction by utilizing a large volume of admission records. Firstly, both a rule-based medical language processing method and a machine learning method (i.e., Conditional Random Fields (CRFs are developed to extract essential patient features from unstructured admission records. After that, state-of-the-art supervised machine learning algorithms are applied to construct MACE prediction models from data. Results: We comparatively evaluate the performance of the proposed approach on a real clinical dataset consisting of 2930 ACS patient samples collected from a Chinese hospital. Our best model achieved 72% AUC in MACE prediction. In comparison of the performance between our models and two well-known ACS risk score tools, i.e., GRACE and TIMI, our learned models obtain better performances with a significant margin. Conclusions: Experimental results reveal that our approach can obtain competitive performance in MACE prediction. The comparison of classifiers indicates the proposed approach has a competitive generality with datasets extracted by different feature extraction methods. Furthermore, our MACE prediction model obtained a significant improvement by comparison with both GRACE and TIMI. It indicates that using admission records can effectively provide MACE prediction service for ACS patients at the early stage of their hospitalizations.

    Recent gene-environment interaction studies suggest that diet may influence an individual's genetic predisposition to cardiovascular risk. We evaluated whether omega-3 fatty acid intake may influence the risk for acute coronary syndrome (ACS) conferred by genetic polymorphisms among patients with early onset ACS. Our population consisted of 705 patients of white European descent enrolled in GENESIS-PRAXY, a multicenter cohort study of patients aged 18-55 years and hospitalized with ACS. We used a case-only design to investigate interactions between the omega-3 index (a validated biomarker of omega-3 fatty acid intake) and 30 single nucleotide polymorphisms (SNPs) robustly associated with ACS. We used logistic regression to assess the interaction between each SNP and the omega-3 index. Interaction was also assessed between the omega-3 index and a genetic risk score generated from the 30 SNPs. All models were adjusted for age and sex. An interaction for increased ACS risk was found between carriers of the chromosome 9p21 variant rs4977574 and low omega-3 index (OR 1.57, 95% CI 1.07-2.32, p = 0.02), but this was not significant after correction for multiple testing. Similar results were obtained in the adjusted model (OR 1.55, 95% CI 1.05-2.29, p = 0.03). We did not observe any interaction between the genetic risk score or any of the other SNPs and the omega-3 index. Our results suggest that omega-3 fatty acid intake may modify the genetic risk conferred by chromosome 9p21 variation in the development of early onset ACS and requires independent replication.

    Patients undergoing acute left main (LM) coronary artery revascularization have a high mortality and natriuretic peptides such as N-terminal pro-B-type (NT-proBNP) have been shown to have prognostic value in patients with acute coronary syndromes. The present study looked at the prognostic value of NT-proBNP in these patients. We studied all consecutive patients undergoing acute LM coronary artery percutaneous coronary intervention between January 2005 and December 2008 in whom NT-proBNP was measured (n=71). We analyzed the clinical characteristics and the short- and long-term outcomes in relation to NT-proBNP level at admission. Median NT-proBNP was 1,364 ng/L, ranging from 46 to 70,000 ng/L. NT-proBNP was elevated in 63 (89%) patients and was ≥1,000ng/L in 42 (59%). Log NT-proBNP (hazard ratio [HR] 3.51, 95% confidence interval [CI] 1.55-7.97, P=0.003) and left ventricular ejection fraction (HR 0.95, 95%CI 0.91-0.99, P=0.007) were predictors for all-cause mortality. Log NT-proBNP was the only independent significant predictor of cardiovascular mortality. In-hospital mortality was 0% for patients with NT-proBNP value for NT-proBNP in patients undergoing acute LM coronary artery intervention.

    Arterial hypertension is an established risk factor for acute coronary syndrome (ACS). Multidetector computed tomography (MDCT) is an accurate and less invasive technique for assessment of the degree of coronary artery luminal narrowing and characterization of coronary atherosclerosis. We therefore aimed to investigate the predictive power of MDCT for future ACS events and compared with traditional parameters in patients with hypertension. One hundred and thirty-four patients (93 men, mean age 70±11 years) with hypertension underwent MDCT for evaluation of coronary artery disease. MDCT analysis focused on the presence of plaques, the degree of stenosis, and the plaque characteristics. Traditional parameters included Framingham risk score, carotid intima-media thickness, and left ventricular mass index. During a mean follow-up of 39±10 months, ACS events occurred in 10 patients, including myocardial infarction (n=3) and unstable angina (n=7). Multivariate analysis identified total number of low attenuation plaques as an independent predictor of ACS events (p<0.001). We demonstrated that non-obstructive low attenuation coronary plaques on MDCT predicted more accurately future ACS events in patients with hypertension than traditional parameters. (author)

In this context, the main risk factor in elderly patients, ie, frailty syndrome, gains special importance. The availability of tools to identify frail people is relevant for both research and clinical purposes. The purpose of this study was to investigate the correlation of a scale for assessing frailty – the Tilburg Frailty Indicator (TFI and its domains (mental and physical – with other research tools commonly used for comprehensive geriatric assessment in patients with ACS.Patients and methods: The study covered 135 people and was carried out in the cardiology ward at T Marciniak Lower Silesian Specialist Hospital in Wroclaw, Poland. The patients were admitted with ACS. ST segment elevation myocardial infarction and non-ST segment elevation myocardial infarction were defined by the presence of certain conditions in reference to the literature. The Polish adaptation of the TFI was used for the frailty syndrome assessment, which was compared to other single measures used in geriatric assessment: the Mini-Mental State Examination (MMSE, the Hospital Anxiety and Depression Scale (HADS, and Katz Index of Independence in Activities of Daily Living (ADLs.Results: The mean TFI value in the studied group amounted to 7.13±2.81 (median: 7, interquartile range: 5–9, range [0, 14]. Significant correlations were demonstrated between the values of the TFI and other scales: positive for HADS (r=0.602, P<0.001 and the reverse for MMSE (r=-0.603, P<0.001 and IADL (r=-0.462, P<0.001.

Pulmonary valve stenosis and hypertrophic cardiomyopathy are the most frequent cardiac abnormalities, the latter being associated with a higher mortality. Here we report for the first time, a case of congenital left main coronary artery atresia in a Noonan syndrome associated with RIT1 variant, leading to unrescued sudden death. This case-report supports the already-suspected severity of the RIT1-related Noonan syndrome compared to average Noonan syndrome, and should encourage clinicians to be very cautious with these patients.

    Type 2 diabetes is highly prevalent in patients with acute coronary syndrome and impacts negatively on health outcomes and self-management. Both conditions share similar risk factors. However, there is insufficient evidence on the effectiveness of combined interventions to promote self-management behaviour for people with diabetes and cardiac problems. Identifying critical features of successful interventions will inform future integrated self-management programmes for patients with both conditions. To assess the evidence on the effectiveness of existing interventions to promote self-management behaviour for patients presenting with acute coronary syndrome and type 2 diabetes in secondary care settings and postdischarge. We searched MEDLINE, PubMed, CINAHL Plus, PsycInfo, Cochrane Library and AMED for randomised controlled trials published between January 2005-December 2014. The search was performed using the following search terms of 'acute coronary syndrome', 'type 2 diabetes' and 'self-management intervention' and their substitutes combined. Of 4275 articles that were retrieved, only four trials met all the inclusion criteria (population, intervention, comparison and outcome) and were analysed. Overall, the results show that providing combined interventions for patients with both conditions including educational sessions supported by multimedia or telecommunication technologies was partially successful in promoting self-management behaviours. Implementation of these combined interventions during patient's hospitalisation and postdischarge was feasible. Intervention group subjects reported a significant improvement in self-efficacy, level of knowledge, glycated haemoglobin, blood pressure and fasting glucose test. However, there are many threats have been noticed around internal validity of included studies that could compromise the conclusions drawn. With limited research in this area, there was no final evidence to support effectiveness of combined

    Full Text Available OBJECTIVES: Clinical characteristics and trends in the outcome of acute coronary syndrome (ACS in patients with prior coronary artery bypass graft surgery (CABG are unclear. The aim of this study was to evaluate clinical characteristics, in-hospital treatment, and outcomes in patients presented with ACS with or without a history of prior CABG over 2 decades. METHODS: Data were derived from hospital-based study for collected data from 1991 through 2010 of patients hospitalized with ACS in Doha, Qatar. Data were analyzed according to their history of prior CABG. Baseline clinical characteristics, in-hospital treatment, and outcome were compared. RESULTS: A total 16,750 consecutive patients with ACS were studied, of which 693 (4.1% had prior CABG. Patients with prior CABG were older (mean 60.5±11 vs. 53±12 years; P = 0.001, more likely to be females and have more cardiovascular risk factors than the non-CABG group. Prior CABG patients had larger infarct size, were less likely to receive reperfusion therapy, early invasive therapy and more likely to receive evidence-based therapies when compared to non-CABG patients. In-hospital mortality and stroke rates were comparable between the 2 groups. Over 2 decades, there was reduction in the in-hospital mortality rates and stroke rates in both groups (CABG, death; 13.2% to 4%, stroke; 1.9% to 0.0%, non-CABG, death; 10% to 3.2%, stroke 1.0% to 0.1%; all, p = 0.001. CONCLUSION: Significant reduction in-hospital morbidity and mortality among ACS patients with prior CABG over a 20-year period.

    The troponin I serum level is widely used in acute coronary syndrome patients for their classification. The qualitative assay is faster and more available than the quantitative assay. The objective was to determine the operating characteristics of a qualitative troponin I assay compared with a quantitative method. This is a prospective observational study and patients suspected to have acute coronary syndrome were enrolled. A rapid troponin I test and a quantitative assay were carried out for each patient on arrival and 6 h after admission. A total of 262 patients were enrolled. The degree of agreement between the second rapid qualitative and quantitative troponin I was excellent (κ=0.946; 95% confidence interval, 0.903-0.989). The sensitivity, specificity, negative predictive value, and positive predictive value of the rapid qualitative troponin I test were 92.6, 100, 96.8, and 100%, respectively. In conclusion, this study reveals an excellent agreement between quantitative and qualitative bedside assays 6 h after admission in a sample of Iranian patients in the emergency department.

    Western studies have suggested that emotional stress and distress impacted on the morbidity and mortality in people following acute coronary events. Symptoms of anxiety and depression have been associated with re-infarction and death, prolonged recovery and disability and depression may precipitate the client's low self-esteem. This study examined perceived anxiety, depression and self-esteem of Hong Kong Chinese clients diagnosed with acute coronary syndrome (ACS) over a 6-month period following hospital admission. To examine: A prospective, repeated measures design with measures taken on two occasions over a 6-month period; (1) within the 1st week of hospital admission following the onset of ACS and (2) at 6 months follow up. Convenient sample of 182 voluntary consented clients admitted with ACS to a major public hospital in Hong Kong who could communicate in Chinese, complete questionnaires, cognitive intact, and were haemodynamically stable and free from acute chest pain at the time of interview. Baseline data were obtained within 1 week after hospital admission. The follow-up data was collected 6 months after hospital discharge. The Chinese version of the Hospital Anxiety and Depression Scale (HADS), State Self-esteem Scale (SSES), and Rosenberg's Self-Esteem Scale (RSES) were used to assess anxiety and depression, state self-esteem, and trait self-esteem, respectively. Findings suggested gender differences in clients' perception in anxiety, depression and self-esteem. Improvements in clients' perception of these variables were evident over the 6-month period following their acute coronary events. The study confirmed the western notion that psychosocial problems are common among coronary clients and this also applies to Hong Kong Chinese diagnosed with ACS. Further studies to explore effective interventions to address these psychosocial issues are recommended.

    Ischaemic heart disease is the leading cause of in-hospital mortality in Sri Lanka. Acute Coronary Syndrome Sri Lanka Audit Project (ACSSLAP) is the first national clinical-audit project that evaluated patient characteristics, clinical outcomes and care provided by state-sector hospitals. ACSSLAP prospectively evaluated acute care, in-hospital care and discharge plans provided by all state-sector hospitals managing patients with ACS. Data were collected from 30 consecutive patients from each hospital during 2-4 weeks window. Local and international recommendations were used as audit standards. Data from 87/98 (88.7%) hospitals recruited 2177 patients, with 2116 confirmed as having ACS. Mean age was 61.4±11.8 years (range 20-95) and 58.7% (n=1242) were males. There were 813 (38.4%) patients with unstable angina, 695 (32.8%) with non-ST-elevation myocardial infarction (NSTEMI) and 608 (28.7%) with ST-elevation myocardial infarction (STEMI). Both STEMI (69.9%) and NSTEMI (61.4%) were more in males (Pacute setting and on discharge. In STEMI, 407 (66.9%) were reperfused; 384 (63.2%) were given fibrinolytics and only 23 (3.8%) underwent primary percutaneous coronary intervention (PCI). Only 42.3 % had thrombolysis in coronary interventions planned. In patients with ACS, aspirin, clopidogrel and statin use met audit standards in acute setting and on discharge. Vast majority of patients with STEMI underwent fibrinolyisis than PCI, due to limited resources. Primary PCI, planned coronary interventions and timely thrombolysis need improvement in Sri Lanka. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Hyperglycemia at admission seems to identify a subgroup of patients with acute coronary syndromes with poorer outcome. The aim of this study was to evaluate the impact of the glycemic variation during hospitalization in long-term mortality in nondiabetic patients. Retrospective study of 2043 consecutive patients without known diabetes mellitus admitted for acute coronary syndrome in a single coronary care unit from May 2007 through August 2013. The population was divided in quartiles regarding glycemia at admission (≤ 90 mg/dL, n = 374; 90-140 mg/dL, n = 1307; 141-180 mg/dL, n = 230; ≥ 181mg/dL, n = 111) and the mortality rate quantified for patients with glycemic variation above/below the mean for their respective quartile. The median follow-up was about 1200 days. The all-cause mortality during follow-up was significantly and successively higher in the upper quartiles (9.1%, 9.7%, 13.5% and 18.9%; P = .007). Multivariate regression analysis showed that hyperglycemia at admission (≥ 181mg/dL) was a strong independent predictor of mortality during follow-up (hazard ratio = 1.74; 95% confidence interval, 1.07-2.8; P = .027). In the fourth quartile (≥ 181mg/dL), the mortality is higher in patients with higher variations of glycemia (37.5% vs 8.5%; P < .001). Hyperglycemia at admission is a predictor of all-cause mortality in our population. The mortality is higher in patients with higher glycemic variations. More studies are needed to confirm these data.

    The incremental prognostic value of plasma levels of C-reactive protein (CRP) in relation to GRACE score has not been established in patients with acute coronary syndrome (ACS) with non-ST segment elevation. To test the hypothesis that CRP measurements at admission increases the prognostic value of GRACE score in patients with ACS. A total of 290 subjects, consecutively admitted for ACS, with plasma material obtained upon admission CRP measurement using a high-sensitivity method (nephelometry) were studied. Cardiovascular outcomes during hospitalization were defined by the combination of death, nonfatal myocardial infarction or nonfatal refractory angina. The incidence of cardiovascular events during hospitalization was 15% (18 deaths, 11 myocardial infarctions, 13 angina episodes) with CRP showing C-statistics of 0.60 (95% CI = 0.51-0.70, p = 0.034) in predicting these outcomes. After adjustment for the GRACE score, elevated CRP (defined as the best cutoff point) tended to be associated with hospital events (OR = 1.89, 95% CI = 0.92 to 3.88, p = 0.08). However, the addition of the variable elevated CRP in the GRACE model did not result in significant increase in C-statistics, which ranged from 0.705 to 0.718 (p = 0.46). Similarly, there was no significant reclassification of risk with the addition of CRP in the predictor model (net reclassification = 5.7 %, p = 0.15). Although CRP is associated with hospital outcomes, this inflammatory marker does not increase the prognostic value of the GRACE score.

To evaluate the prognostic utility of serum 25-hydroxyvitamin D [25(OHD] in 871 patients with suspected acute coronary syndrome (ACS and to assess the seasonal correlation between 25(OHD and the omega-3 index in 456 ACS patients from southwestern Norway. Results. In the univariate analysis the hazard ratio (HR at 2-year follow-up for all-cause mortality in the highest as compared to the lowest quartile of 25(OHD in the total population was 0.61 (95% confidence interval (CI, 0.37–1.00, P=0.050. At 7-year follow-up, the corresponding HR for all-cause mortality was 0.66 (95% CI, 0.49–0.90, P=0.008, and for females alone 0.51 (95% CI, 0.32–0.83, P=0.006. Quartile survival did not differ in the multivariable analysis, whereas 25(OHD < 40 nM (<16 ng/mL was found to be independently related to mortality. Seasonal differences in 25(OHD, but not for the omega-3 index, were noted, and the two biomarkers were positively correlated, especially during winter-spring; Pearson’s correlation coefficient was 0.358, P<0.001. Conclusion. Vitamin D levels are related to survival, especially in females, and correlate with the omega-3 index.

    India has the highest burden of acute coronary syndromes worldwide. Apart from certain lipid alterations that have been established to be definite risk factors, low level of adiponectin, high levels of resistin, and IL-6 have been shown to be risk factors for cardiovascular events. Insulin resistance is also a significant predictor of poor outcome in patients admitted with ACS. 69 male patients with ACS and 70 age-matched healthy males were recruited in the study. Insulin, total adiponectin, resistin, and IL-6 levels were assayed in all study subjects. Indices of insulin resistance and novel adipokine indices were calculated using standard formulae. Multiple logistic regression analysis was done to find out the best predictor of ACS. Resistin, IL-6, insulin resistance indices, AR index, and IRAR index were found to be significantly higher, while insulin sensitivity indices and total adiponectin were found to be lower in cases, as compared with controls (p < 0.001). Insulin resistance was found to be higher in the admission sample, when compared to the fasting sample in patients with ACS (p = 0.01). On multivariate logistic regression analysis, HOMA-IR and AR index were found to be significantly associated with ACS. AR index was the best independent predictor of ACS, with the highest odds ratio (AR index: adjusted OR 17.528, p < 0.0001 versus HOMA-IR: adjusted OR 1.146, p = 0.001). The present results implicate that adipokines are significantly associated with pathogenesis of ACS, warranting adequate and early appropriate treatment to reverse this metabolic dysregulation. In our study, AR index was the best predictor of ACS. Hence, the novel AR index might be useful in routine clinical practice for screening persons with increased risk of future development of ACS.

    Full Text Available Abstract Background Studies of chronic diseases are associated with a financial burden on households. We aimed to determine if survivors of acute coronary syndrome (ACS experience household economic burden and to quantify any potential burden by examining level of economic hardship and factors associated with hardship. Methods Australian patients admitted to hospital with ACS during 2-week period in May 2012, enrolled in SNAPSHOT ACS audit and who were alive at 18 months after index admission were followed-up via telephone/paper survey. Regression models were used to explore factors related to out-of-pocket expenses and economic hardship. Results Of 1833 eligible patients at baseline, 180 died within 18 months, and 702 patients completed the survey. Mean out-of-pocket expenditure (n = 614 in Australian dollars was A$258.06 (median: A$126.50 per month. The average spending for medical services was A$120.18 (SD: A$310.35 and medications was A$66.25 (SD: A$80.78. In total, 350 (51 % of patients reported experiencing economic hardship, 78 (12 % were unable to pay for medical services and 81 (12 % could not pay for medication. Younger age (18–59 vs ≥80 years (OR: 1.89, no private health insurance (OR: 2.04, pensioner concession card (OR: 1.80, residing in more disadvantaged area (group 1 vs 5 (OR: 1.77, history of CVD (OR: 1.47 and higher out-of-pocket expenses (group 4 vs 1 (OR: 4.57 were more likely to experience hardship. Conclusion Subgroups of ACS patients are experiencing considerable economic burden in Australia. These findings provide important considerations for future policy development in terms of the cost of recommended management for patients.

    Full Text Available Background: Uric acid is an independent risk factor for cardiovascular disease. Hospital admission for ischemic heart disease (IHD is increasing rapidly in our country. Although studies were conducted abroad regarding association of serum uric acid with in-hospital outcomes in patients with acute coronary syndrome (ACS, no data is yet available to show the association in our country. Objective: The objective of this study was to assess the association of serum uric acid level on admission with in-hospital outcomes of the patients with ACS. Materials and Methods: This cross sectional comparative study was done in the Department of Cardiology, Dhaka Medical College Hospital (DMCH from January to December 2012. After proper ethical consideration total 93 ACS patients were enrolled in the study by nonrandom sampling. Serum uric acid of all subjects was measured within 24 hours of admission. Then in-hospital outcomes were observed in all subjects. Results: The frequency of hyperuricemia among ACS patients was 24.7% (22.54% in male and 31.82% in female. Hyperuricemic patients significantly developed heart failure (30.4% vs 11.4%, p=0.032 and conduction defect (13.0% vs 1.4%, p=0.017 than normouricemic subjects. The mean ejection fraction was significantly lower in hyperuricemic patients than patients with normal uric acid level (50.87 ± 10.27% vs 55.94 ± 6.66%. The mean ± SD duration of hospital stay of hyperuricemic group was significantly longer in patients with ACS (8.26 ± 1.18 vs 7.51±1.18 days, p=0.010. Conclusion: The measurement of serum uric acid level, an easily available and inexpensive biochemical tool, might turn out as a valuable risk marker for prediction of in-hospital outcomes in patients with ACS.

    Few data are so far available on the relation between increased glucose values and insulin resistance and mortality at short-term in patients with acute heart failure (AHF). The present investigation, performed in 409 consecutive patients with AHF complicating acute coronary syndrome (ACS), was aimed at assessing the prognostic role of admission glycaemia and acute insulin resistance (as indicated by the Homeostatic Model Assessment - HOMA index) for death during Intensive Cardiac Care (ICCU) stay. Admission glucose tertiles were considered. In our series, diabetic patients accounted for the 33%. Patients in the third glucose tertiles exhibited the lowest LVEF (both on admission and at discharge), a higher use of mechanical ventilation, intra-aortic balloon pump and inotropic drugs and the highest in-ICCU mortality rate. In the overall population, hyperglycaemic patients (both diabetic and non diabetic) were 227 (227/409, 55.5%). Admission glycaemia was an independent predictor of in-ICCU mortality, together with admission LVEF and eGFR, while acute insulin resistance (as indicated by HOMA-index) was not associated with early death. The presence of admission hyperglycaemia in non-diabetic patients was independently associated with in-ICCU death while hyperglycaemia in diabetic patients was not. According to our results, hyperglycaemia is a common finding in patients with ACS complicated by AHF and it is an independent predictor of early death. Non-diabetic patients with hyperglycaemia are the subgroup with the highest risk of early death.

    Acute coronary syndrome (ACS) is an important public health problem around the world. Since there is a considerable seasonal fluctuation in the incidence of ACS, climatic temperature may have an impact on the onset of this disease. The objective of this study was to assess the relationship between the average daily temperature, diurnal temperature range and emergency room (ER) admissions for ACS in an ER in Taichung City, Taiwan. A longitudinal study was conducted which assessed the correlation of the average daily temperature and the diurnal temperature range to ACS admissions to the ER of the city’s largest hospital. Daily ER admissions for ACS and ambient temperature were collected from 1 January 2000 to 31 March 2003. The Poisson regression model was used in the analysis after adjusting for the effects of holiday, season, and air pollutant concentrations. The results showed that there was a negative significant association between the average daily temperature and ER admissions for ACS. ACS admissions to the ER increased 30% to 70% when the average daily temperature was lower than 26.2°C. A positive association between the diurnal temperature range and ACS admissions was also noted. ACS admissions increased 15% when the diurnal temperature range was over 8.3°C. The data indicate that patients suffering from cardiovascular disease must be made aware of the increased risk posed by lower temperatures and larger changes in temperature. Hospitals and ERs should take into account the increased demand of specific facilities during colder weather and wider temperature variations.

    The aim of this study was to evaluate the relationship between weather conditions and daily emergency ambulance calls for acute coronary syndromes (ACS). The study included data on 3631 patients who called the ambulance for chest pain and were admitted to the department of cardiology as patients with ACS. We investigated the effect of daily air temperature ( T), barometric pressure (BP), relative humidity, and wind speed (WS) to detect the risk areas for low and high daily volume (DV) of emergency calls. We used the classification and regression tree method as well as cluster analysis. The clusters were created by applying the k-means cluster algorithm using the standardized daily weather variables. The analysis was performed separately during cold (October-April) and warm (May-September) seasons. During the cold period, the greatest DV was observed on days of low T during the 3-day sequence, on cold and windy days, and on days of low BP and high WS during the 3-day sequence; low DV was associated with high BP and decreased WS on the previous day. During June-September, a lower DV was associated with low BP, windless days, and high BP and low WS during the 3-day sequence. During the warm period, the greatest DV was associated with increased BP and changing WS during the 3-day sequence. These results suggest that daily T, BP, and WS on the day of the ambulance call and on the two previous days may be prognostic variables for the risk of ACS.

    Full Text Available Background: According to some international studies, patients with acute coronary syndrome (ACS and increased left atrial volume index (LAVI have worse long-term prognosis. However, national Brazilian studies confirming this prediction are still lacking. Objective: To evaluate LAVI as a predictor of major cardiovascular events (MCE in patients with ACS during a 365-day follow-up. Methods: Prospective cohort of 171 patients diagnosed with ACS whose LAVI was calculated within 48 hours after hospital admission. According to LAVI, two groups were categorized: normal LAVI (≤ 32 mL/m2 and increased LAVI (> 32 mL/m2. Both groups were compared regarding clinical and echocardiographic characteristics, in- and out-of-hospital outcomes, and occurrence of ECM in up to 365 days. Results: Increased LAVI was observed in 78 patients (45%, and was associated with older age, higher body mass index, hypertension, history of myocardial infarction and previous angioplasty, and lower creatinine clearance and ejection fraction. During hospitalization, acute pulmonary edema was more frequent in patients with increased LAVI (14.1% vs. 4.3%, p = 0.024. After discharge, the occurrence of combined outcome for MCE was higher (p = 0.001 in the group with increased LAVI (26% as compared to the normal LAVI group (7% [RR (95% CI = 3.46 (1.54-7.73 vs. 0.80 (0.69-0.92]. After Cox regression, increased LAVI increased the probability of MCE (HR = 3.08, 95% CI = 1.28-7.40, p = 0.012. Conclusion: Increased LAVI is an important predictor of MCE in a one-year follow-up.

The QoL was assessed using the MacNew Heart Disease Health-Related Quality of Life questionnaire. The group of females scored lower in all the domains of the MacNew Heart Disease Health-Related Quality of Life questionnaire in the initial measurement (B1, in the measurement after 6 months (B2, and in the long-term follow-up measurement (36 months – B3. Despite the fact that both groups achieved improved QoL, its values were higher in the males. The average growth rate of the QoL score in the period from the sixth month to 36th month was higher in females than in males. In the univariate and multivariate analyses, significant independent predictors with a negative influence on the long-term QoL score included female sex (Ρ=−0.190, β=−0.21, age >60 years (Ρ=−0.255, β=−0.186, and diabetes (Ρ=−0.216, β=−0.216.Conclusion: In a 36-month follow-up of ACS patients treated with PCI, there were no statistically significant differences in QoL between sexes. In the entire cohort, there was improvement in QoL, which was higher in the case of the females studied. For the entire group, significant independent determinants of lower QoL 3

    We hypothesized that matrix metalloproteinase (MMP)-2, -9, and tissue inhibitor metalloproteinase-1, -2 (TIMP-1, -2) would be abnormal in diabetes and in acute coronary syndromes (ACS). We measured MMP-2, -9, and TIMP-1, -2 plasma levels in healthy subjects (controls), in type 2 diabetic patients, in nondiabetic patients with ACS (ACS) and in diabetic patients with ACS (DACS). We enrolled 165 controls, 181 diabetic patients, 78 ACS, and 46 DACS. We measured also BMI (body mass index), HbA(1c) (glycated hemoglobin) FPG (fasting plasma glucosa), FPI (fasting plasma insulin), HOMA index (homeostasis model assessment index), SBP (systolic blood pressure), DBP (diastolic blood pressure), TC (total cholesterol), LDL-C (low density lipoprotein cholesterol), HDL-C (high-density lipoprotein cholesterol), Tg (triglycerides), Lp(a) (lipoprotein(a)) PAI-1 (plasminogen activator inhibitor-1), Hct (homocysteine), Fg (fibrinogen), and hs-CRP (high-sensitivity C-reactive protein). A significant increase of BMI was observed in the diabetic group, in ACS and DACS patients compared to controls. A significant increase of SBP and DBP resulted in the diabetic and DACS groups, while only SBP improvement was present in ACS patients with respect to controls. A decrease in SBP and DBP was observed in the ACS group, while SBP variation was present in DACS patients compared to diabetics, and DBP increase was obtained in the DACS group with respect to ACS patients. TC, LDL-C, Tg, and Lp(a) increase was present in diabetics, while TC, Tg, and Lp(a) improvement was present in ACS and DACS patients with a significant decrease of HDL-C levels in diabetic, ACS, and DACS groups compared to controls. A decrease in LDL-C was obtained in ACS and DACS groups, while HDL-C increase was observed in these patients with respect to diabetics. Tg levels were higher in the DACS group compared to diabetics and ACS patients, respectively. Increases in PAI-1, Hct, Fg, and hs-CRP were present in diabetic and DACS

    Asymptomatic acute ischemic stroke (aAIS) following primary percutaneous coronary intervention (p-PCI) in patients with acute coronary syndrome (ACS) has not been studied in detail. Of 75 patients who underwent p-PCI, 26 (34.7%) developed aAIS as determined by diffusion-weighted magnetic resonance imaging (MRI). Including the approach to the coronary artery (via lower limb or right upper limb), 23 factors were compared between patients with (n=26) and without (n=49) aAIS. Age, hypertension, smoking, plasma glucose levels, Killip grade, right coronary artery (RCA) as culprit vessel, percutaneous coronary intervention (PCI) time, and the frequency of device insertion into the coronary artery differed in a statistically significant manner. However, multivariate analysis showed that the RCA (odds ratio 3.477) and the frequency of device insertion (1.375) were independent factors linked to the incidence of aAIS. Moreover, anterior or posterior location and left or right cerebral circulation of aAIS were equivalent in both approaches. Cranial MRI images following emergency PCI revealed that 34.7% of the patients with ACS had aAIS that might be caused by manipulating the catheter or devices in the ascending aorta, micro-air bubble embolism during injection, or micro-thrombus embolism derived from the ACS lesions during the PCI procedure.

    Full Text Available In this study we examined the association between WBC, CRP and IL-6 plasma concentrations and clinical and biochemical parameters in patients with CAD. Many reports have been published on associations between inflammation markers and cardiovascular diseases. Therefore we did not aim to confirm that inflammation is a significant risk factor of CAD, but to explore associations between inflammation and other features (including metabolic syndrome and arrhythmia in patients already diagnosed with CAD. IL-1beta plasma concentrations were too low for reliable measurement in our patients. Increased levels of WBC, CRP and IL-6 were associated with heart failure, severity of CAD symptoms, severe past ventricular arrhythmia, lower left ventricle ejection fraction, higher left ventricle mass index or end-diastolic volume, metabolic syndrome components and higher number of smoking pack-years. In multivariate analyses the common independent predictors of higher WBC, CRP and IL-6 were: symptoms of advanced CAD, ventricular arrhythmia, obesity and dyslipidaemia. The relatively high proportion of patients with heart failure or an implanted ICD and severe ventricular arrhythmias in the study group reflects the profile of the Department of Cardiology, which is an academic tertiary referral centre. Advanced CAD symptoms (reflected by higher CCS class and presence of heart failure, as a result of functional heart damage related to ischemia, were independent predictors of higher levels of inflammation markers. Interestingly, echocardiography parameters were not significant predictors of inflammation markers in multivariate models including clinical symptoms. This association may indicate that the markers reflect the increasing intensity of inflammation during the natural clinical course of progressing CAD. It would be very interesting to investigate in prospective studies whether coronary revascularization, which alleviates CAD symptoms and improves cardiovascular

    Full Text Available Abstract Background Coronary artery disease is the leading cause of death in industrialized countries and most patients with diabetes die from complications of atherosclerosis. The objective of this study was to determine the presence of diabetes mellitus and other conventional coronary heart disease risk factors (cigarette smoking, hypertension and hyperlipidemia in patients with acute coronary events in an Iranian population. Methods The study included 514 patients with unstable angina or myocardial infarction (MI out of 720 patients admitted to CCU ward of a general hospital from March 2003 to March 2005. History of diabetes, hypertension and cigarette smoking, demographic indices, coronary heart disease and diabetes mellitus treatment, myocardial enzymes, serum triglycerides (TG and cholesterol and fasting and non fasting blood glucose levels and HbA1C of diabetics were recorded of admission sheets. The data were structured to appropriate one way ANOVA, T tests, and chi square test with SPSS 13 product for windows. Results Out of all patients 35.8% were female, 30% were diabetics (Duration 13.4 ± 8.7 years, 42% were smoker and 91% were hypertensive. Twenty four percent had MI and 76% had unstable angina. MI was significantly higher in diabetic patients (36.4% vs. 19.2%, P Conclusion In this study 19 out of 20 patients with acute coronary event have at least one of conventional cardiac risk factors. Diabetes and hypertension are leading risk factors, which may directly or indirectly interfere and predict more serious complications of coronary heart disease.

    Acute coronary syndrome (ACS) is considered one of the main causes of death worldwide. Contradictory findings concerning the impact of the angiotensin-converting enzyme (ACE) gene on cardiovascular diseases have been reported. Previous conclusions point out that the variability in results depends on ethnicity and genetic polymorphisms to determine the association of rs4340 polymorphisms of the ACE gene and ACE circulating levels in ACS. Genotyping of rs4340 polymorphisms was performed in a total of 600 individuals from Western Mexico divided into two groups: the ACS and the control group (CG). The polymorphisms were identified by polymerase chain reaction. Serum ACE concentration was determined by enzyme-linked immunosorbent assay. D/D carriers had higher ACE levels than I/I carriers (3.6 vs 2.8 ng/mL, P ACE concentration levels; however, the polymorphism was not associated with ACS.

    AIMS Our study aimed to examine the impact of concomitant use of proton pump inhibitors (PPIs) with clopidogrel on the cardiovascular outcomes of patients with acute coronary syndrome (ACS). Furthermore, we sought to quantify the effects of five individual PPIs when used concomitantly with clopidogrel. METHODS We conducted a retrospective cohort study of patients who were newly hospitalized for ACS between 1 January 2006 and 31 December 2007 retrieved from the Taiwan National Health Insurance Research Database (NHIRD) and who were prescribed clopidogrel (n= 37 099) during the follow-up period. A propensity score technique was used to establish a matched cohort in 1:1 ratio (n= 5173 for each group). The primary clinical outcome was rehospitalization for ACS, while secondary outcomes were rehospitalization for percutaneous transluminal coronary angioplasty (PTCA) with stent, PTCA without stent and revascularization (PTCA or coronary artery bypass graft surgery) after the discharge date for the index ACS event. RESULTS The adjusted hazard ratio of rehospitalization for ACS was 1.052 (95% confidence interval, 0.971–1.139; P= 0.214) in the propensity score matched cohort. Among all PPIs, only omeprazole was found to be statistically significantly associated with an increased risk of rehospitalization for ACS (adjusted hazard ratio, 1.226; 95% confidence interval, 1.066–1.410; P= 0.004). Concomitant use of esomeprazole, pantoprazole, rabeprazole and lansoprazole did not increase the risk. CONCLUSIONS Our study indicated no statistically significant increase in the risk of rehospitalization for ACS due to concurrent use of clopidogrel and PPIs overall. Among individual PPIs, only omeprazole was found to be statistically significantly associated with increased risk of rehospitalization for ACS. PMID:22364155

    Full Text Available Abstract Background Genome-wide association studies (GWAS have identified new candidate genes for the occurrence of acute coronary syndrome (ACS, but possible effects of such genes on survival following ACS have yet to be investigated. Methods We examined 95 polymorphisms in 69 distinct gene regions identified in a GWAS for premature myocardial infarction for their association with post-ACS mortality among 811 whites recruited from university-affiliated hospitals in Kansas City, Missouri. We then sought replication of a positive genetic association in a large, racially diverse cohort of myocardial infarction patients (N = 2284 using Kaplan-Meier survival analyses and Cox regression to adjust for relevant covariates. Finally, we investigated the apparent association further in 6086 additional coronary artery disease patients. Results After Cox adjustment for other ACS risk factors, of 95 SNPs tested in 811 whites only the association with the rs6922269 in MTHFD1L was statistically significant, with a 2.6-fold mortality hazard (P = 0.007. The recessive A/A genotype was of borderline significance in an age- and race-adjusted analysis of the entire combined cohort (N = 3095; P = 0.052, but this finding was not confirmed in independent cohorts (N = 6086. Conclusions We found no support for the hypothesis that the GWAS-identified variants in this study substantially alter the probability of post-ACS survival. Large-scale, collaborative, genome-wide studies may be required in order to detect genetic variants that are robustly associated with survival in patients with coronary artery disease.

    Rapid progress has been made in the treatment of Marfan syndrome. Today, the treatment is relatively established and the results have also improved. Even if surgery is performed, however, vascular lesions may recur late after operation and late prognosis is poor considering the age of patients. Issues such as whether a reoperation should be conducted or how the late results might be improved are subjects of debate. Based on an analysis of recent late data, we have performed operations according to the new treatment policy, and here report the results. A total of 203 consecutive operations were conducted in 141 patients with Marfan syndrome who underwent surgery for aortic aneurysm at our department between February 1973 and August 2001. The mean age of patients was 39 (11 years with a male/female ratio of 95:46. At the first operation, 72 patients were diagnosed with annuloaortic ectasia (AAE), 17 patients with AAE + chronic dissection (DeBakey I), 14 patients with AAE + chronic dissection (DeBakey II), 6 patients with AAE + acute dissection (Stanford A), 11 patients with AAE + dissection (DeBakey III), 9 patients with dissection (DeBakey III) only, 3 patients with AAE + abdominal aortic aneurysm only, and 2 patients with abdominal aortic aneurysm only. The cause of reoperation were a new lesion in 17 patients, dissection in 13 patients and a true aneurysm in 4 patients. In 36 patients, an increase in the remaining lesion occurred or a scheduled stage 2 operation was performed. Reoperation was performed following the Bentall operation in 7 patients, dehiscence of the anastomotic region of the coronary artery in 5 patients, aneurysm of the anastomotic region of the coronary artery in 1 patients, and infection of the artificial valve with aneurysm of the anastomotic region of the coronary artery in 1 patient. Hospital deaths were reported in 8 (6%) patients who underwent composite valve graft replacement (including simultaneous arch replacement) for AAE. Hospital

    Full Text Available Caroline Schmidt-Lucke, Heinz-Peter SchultheissCharité Medical University Berlin, Campus Benjamin Franklin, Dept. of Cardiology and Pulmology, GermanyAbstract: Non-ST elevation acute coronary syndrome (NSTE-ACS refers to a cardiovascular disorder characterized by intracoronary thrombus formation on a disrupted atherosclerotic plaque with partial or transient occlusion. Generation of thrombin resulting from exposure of collagen leads to activation of platelets and conversion of fibrinogen to fibrin, thus forming a platelet-rich thrombus. The main therapeutic objective is to protect the patient from thrombotic complications, independent of the choice of antithrombotic agents. The management of NSTE myocardial infarction (MI is constantly evolving. For primarily conservative strategy, enoxaparin has been proven superior to unfractioned heparin (UFH. With early invasive strategy providing better clinical outcome compared with conservative strategy, the effectiveness of enoxaparin in reducing death and MI rates is now being reconsidered in the era of poly-pharmacotherapy, early percutaneous coronary interventions and drug eluting stents. Bleeding complications can be minimized by avoiding cross-over from UFH to enoxaparin or vice versa, or by reducing the dosage of enoxaparin. We review the studies of enoxaparin and discuss its current role in the contemporary treatment of NSTE-ACS.Keywords: low-molecular weight heparin, NSTEMI, treatment

    Polyunsaturated fatty acids (PUFAs) are intrinsic cell membrane components and closely involved in neurotransmission and receptor function. Lower omega-3 levels are associated with increased risk of coronary artery disease (CAD), increases in cardiac events in CAD patients, and depression. We sought to examine relationships between depression and serum levels of omega-3 and omega-6 PUFAs in patients recovering from acute coronary syndromes (ACS). We carried out a case-control study of serum PUFA levels and current major depression in 54 age- and sex-matched pairs approximately 2 months following ACS. Depressed patients had significantly lower concentrations of total omega-3 and docosahexaenoic acid (DHA), and higher ratios of arachidonic acid (AA) to DHA, AA to eicosapentaenoic acid (EPA), and n-3 to n-6 than controls. There were no baseline differences in any potential risk or protective factors for depression. Results are consistent with previous reports in depressed patients without CAD, and with literature concerning omega-3 levels and risk of CAD events. Dietary, genetic, and hormonal factors may all play a role in both depression and CAD. Both prospective studies and randomized trials are needed to help clarify the interrelationships.

    Full Text Available Background: Coronary heart disease (CHD is the main leading cause of morbidity and mortality in patients with diabetes mellitus. Hyperglycemia on admission was associated with a worse outcome for all patients admitted with ACS. Aim: To correlate the relationship between hyperglycemia with acute coronary syndrome and poor outcome. Methodology: Clinical evaluation of the patients were carried out on arrival to Emergency Department regarding: Initial assessment of patient general condition either stable or not through; ABCDE (air way and cervical spine control, breathing, circulation, neurological dysfunction and exposure. Then determine the characters and types of chest pain. Assess the condition of the patients either stable or unstable which will determine the needed investigations and plane of management. Results: the mortality was higher in patients with RBG more than 300 mg/dl (68.4 %, (10.5 % of the patients had ranged from 250 ─ < 300 mg/dl, and the patients had ranged from 200 ─ < 250 mg/dl were (10.5 %.

    Most patients with acute coronary syndrome (ACS) are treated with statins, which reduce atherogenic triglyceride-rich lipoproteins. It is uncertain whether triglycerides predict risk after ACS on a background of statin treatment. This study examined the relationship of fasting triglyceride levels to outcomes after ACS in patients treated with statins. Long-term and short-term relationships of triglycerides to risk after ACS were examined in the dal-OUTCOMES trial and atorvastatin arm of the MIRACL (Myocardial Ischemia Reduction with Acute Cholesterol Lowering) trial, respectively. Analysis of dal-OUTCOMES included 15,817 patients (97% statin-treated) randomly assigned 4 to 12 weeks after ACS to treatment with dalcetrapib (a cholesteryl ester transfer protein inhibitor) or placebo and followed for a median 31 months. Analysis of MIRACL included 1,501 patients treated with atorvastatin 80 mg daily beginning 1 to 4 days after ACS and followed for 16 weeks. Fasting triglycerides at initial random assignment were related to risk of coronary heart disease death, nonfatal myocardial infarction, stroke, and unstable angina in models adjusted for age, sex, hypertension, smoking, diabetes, high-density lipoprotein cholesterol, and body mass index. Fasting triglyceride levels were associated with both long-term and short-term risk after ACS. In dal-OUTCOMES, long-term risk increased across quintiles of baseline triglycerides (p175/≤80 mg/dl) was 1.61 (95% confidence interval: 1.34 to 1.94). There was no interaction of triglycerides and treatment assignment on the primary outcome. In the atorvastatin group of MIRACL, short-term risk increased across tertiles of baseline triglycerides (p=0.03), with a hazard ratio of 1.50 [corrected] (95% confidence interval: 1.05 to 2.15) in highest/lowest tertiles (>195/≤135 mg/dl). The relationship of triglycerides to risk was independent of low-density lipoprotein cholesterol in both studies. Among patients with ACS treated effectively

METHODS: A cross-sectional study was conducted on patients with typical angina and positive exercise tolerance test undergoing coronary angiography in our center. 342 consecutive patients with CSX were enrolled into this study and were matched regarding age and sex with 342 patients with acute coronary syndrome (ACS and also 342 patients with chronic stable angina (SA. Cardiovascular risk factors as well as biochemistry profile of the patients were recorded. RESULTS: Mean age of the studied patients was 53.0 years and 41.5% were male. There was no significant difference between the CSX patients and CAD patients regarding body mass index (BMI. Frequency of diabetes mellitus, hyperlipidemia, smoking, family history of premature CAD and hypertension was significantly lower in patients with CSX than ACS and SA patients. Patients with CSX had significantly higher levels of high-density lipoprotein cholesterol (HDL-cholesterol than comparators while the levels of low-density lipoprotein cholesterol (LDL-cholesterol, total cholesterol, triglyceride and fasting blood sugar (FBS were significantly lower in patients with CSX than CAD patients. CONCLUSION: The present study demonstrated that CSX patients had substantially lower frequency of all conventional CVD risk factors than patients with obstructive CAD. This might aid in developing novel scoring systems or appropriateness criteria for angiographic evaluation of patients with typical angina and positive exercise test in order to reduce the rate of negative results.   Keywords: Cardiac Syndrome X, Microvascular Dysfunction

    Patients with nephrotic syndrome are at risk of developing thrombosis in both veins and arteries. Various manifestations in different organs have been reported. Thrombi in heart seen, associated with multi organ thrombosis have been reported on autopsy earlier, but only once in a living patient with nephrotic syndrome. Here, we report a 13 years old boy with steroid-resistant nephrotic syndrome, who developed an asymptomatic but potentially hazardous large intracardiac thrombus. The child developed nephrotic syndrome at the age of 9 years and had multiple recurrences. At the age of 13 years, he developed myocardial infarction (MI) due to embolism from a large intracardiac thrombus. Later on, he was treated with heparin and warfarin anticoagulation. (author)

    In patients with acute coronary syndrome (ACS) who underwent coronary arteries revascularization, violations of hemodynamics, metabolism and heart rate variability often develop in the postoperative period, therefore, the goal of the study was to establish the features of disturbances and the effectiveness of correction of left ventricular systolic and diastolic dysfunction and heart rate variability in stages of cardiorehabilitation in patients with acute coronary syndrome who underwent coronary arteries revascularization. The experimental group included 40 patients with ACS in the postoperative period who underwent balloon angioplasty and stenting of the coronary arteries (25 patients with ST-segment elevation ACS and 15 patients without ST-segment elevation ACS). The age of examined patients was 37 to 74 years, an average of 52.6±6.7 years. The control group consisted of 20 patients, comparable in age and clinico-laboratory manifestations of ACS, who underwent drug treatment with direct anticoagulants, double antiplatelet therapy, β-blockers, ACE inhibitors and statins. Clinical efficacy of cardiorespiratory process in patients of both groups was assessed by the dynamics of general clinical symptoms and parameters of natriuretic propeptide, systolic and diastolic function of the left ventricle and heart rate variability. In the initial state, clinical and laboratory-instrumental signs of myocardial ischemia disappear in patients with ACS undergoing surgical revascularization of the coronary arteries, but clinical and subclinical manifestations of heart failure were diagnosed. The use of the accelerated program of cardiac rehabilitation already during the first month of studies leads to a decreasement of the signs of systolic and diastolic dysfunction, the level of NT-proBNP and improve in the variability of the heart rhythm wich significantly improves the life quality of patients with ACS. To monitor the effectiveness and safety of cardiac rehabilitation in

    The HEART score is a simple and effective tool to predict short-term major adverse cardiovascular events in patients suspected of acute coronary syndrome. Patients are assigned to three risk categories using History, ECG, Age, Risk factors and Troponin (HEART). The purpose is early rule out and discharge is considered safe for patients in the low risk category. Its performance in patients of Asian ethnicity is unknown. We evaluated the performance of the HEART score in patients of Caucasian, Chinese, Indian and Malay ethnicity. The HEART score was assessed retrospectively in 3456 patients presenting to the emergency department with suspected acute coronary syndrome (1791 Caucasians, 1059 Chinese, 344 Indians, 262 Malays), assigning them into three risk categories. The incidence of major adverse cardiovascular events within six weeks after presentation was similar between the ethnic groups. A smaller proportion of Caucasians was in the low risk category compared with Asians (Caucasians 35.8%, Chinese 43.5%, Indians 45.3%, Malays 44.7%, p<0.001). The negative predictive value of a low HEART score was comparable across the ethnic groups, but lower than previously reported (Caucasians 95.3%, Chinese 95.0%, Indians 96.2%, Malays 96.6%). Also the c-statistic for the HEART score was not significantly different between the groups. These results show that the overall performance of the HEART score is equal among Caucasian and Asian ethnic groups. The event rate in the low risk group, however, was higher than reported in previous studies, which queries the safety of early discharge of patients in the low risk category.

    Non-ST elevation acute coronary syndrome (NSTE-ACS) imposes a significant health and economic burden on a society. Anticoagulants are recommended as standard therapy by various clinical practice guidelines. Fondaparinux was introduced and evaluated in a number of large randomised, controlled trials. This study therefore aimed to determine the cost-effectiveness of fondaparinux versus enoxaparin in the treatment of NSTE-ACS in Thailand. A two-part construct model comprising a one-year decision tree and a Markov model was developed to capture short and long-term costs and outcomes from the perspective of provider and society. Effectiveness data were derived from OASIS-5 trial while bleeding rates were derived from the Thai Acute Coronary Syndrome Registry (TACSR). Costs data were based on a Thai database and presented in the year of 2013. Both costs and outcomes were discounted by 3% annually. A series of sensitivity analyses were performed. The results showed that compared with enoxaparin, fondaparinux was a cost-saving strategy (lower cost with slightly higher effectiveness). Cost of revascularisation with major bleeding had a greater impact on the amount of cost saved both from societal and provider perspectives. With a threshold of 160,000 THB ((4,857.3 USD) per QALY in Thailand, fondaparinux was about 99% more cost-effective compared with enoxaparin. Fondaparinux should be considered as a cost-effective alternative when compared to enoxaparin for NSTE-ACS based on Thailand's context, especially in the era of limited healthcare resources.

    Full Text Available Shih-Yin Chen,1 Concetta Crivera,2 Michael Stokes,1 Luke Boulanger,1 Jeffrey Schein2 1United BioSource Corporation, Lexington, MA, USA; 2Janssen Scientific Affairs, LLC, Raritan, NJ, USA Objective: To evaluate the clinical and economic burden of acute coronary syndrome (ACS, a common cardiovascular illness, in the Medicare population. Methods: Data from the Medicare Current Beneficiary Survey were analyzed. Patients with incident hospitalization for ACS without similar events during the 6 months prior were included. Outcomes evaluated included inpatient mortality, 30-day mortality and readmission, subsequent hospitalization events, and total direct health care costs. Sample population weights were applied, accounting for multistage sampling design to obtain nationally representative estimates for the US Medicare population. Results: Between March 1, 2002 and December 31, 2006, we identified 795 incident ACS patients (mean age 76 years; 49% male representing 2,542,211 Medicare beneficiaries. The inpatient mortality rate was 9.71% and the 30-day mortality ranged from 10.96% to 13.93%. The 30-day readmission rate for surviving patients was 18.56% for all causes and 17.90% for cardiovascular disease (CVD-related diagnoses. The incidence of death since admission was 309 cases per 1000 person–years. Among patients discharged alive, the incidence was 197 for death, 847 for CVD-related admission, and 906 for all-cause admission. During the year when the ACS event occurred, mean annual total direct health care costs per person were US$50,458, with more than half attributable to inpatient hospitalization ($27,609. Conclusion: In this national representative Medicare population, we found a substantial clinical and economic burden for ACS. These findings suggest a continuing unmet medical need for more effective management of patients with ACS. The continuous burden underscores the importance of development of new interventions and/or strategies to

    Full Text Available Abstract Background: BNP has been extensively evaluated to determine short- and intermediate-term prognosis in patients with acute coronary syndrome, but its role in long-term mortality is not known. Objective: To determine the very long-term prognostic role of B-type natriuretic peptide (BNP for all-cause mortality in patients with non-ST segment elevation acute coronary syndrome (NSTEACS. Methods: A cohort of 224 consecutive patients with NSTEACS, prospectively seen in the Emergency Department, had BNP measured on arrival to establish prognosis, and underwent a median 9.34-year follow-up for all-cause mortality. Results: Unstable angina was diagnosed in 52.2%, and non-ST segment elevation myocardial infarction, in 47.8%. Median admission BNP was 81.9 pg/mL (IQ range = 22.2; 225 and mortality rate was correlated with increasing BNP quartiles: 14.3; 16.1; 48.2; and 73.2% (p 72 years (OR = 3.79, 95% CI = 1.62-8.86, p = 0.002, BNP ≥ 100 pg/mL (OR = 6.24, 95% CI = 2.95-13.23, p < 0.001 and estimated glomerular filtration rate (OR = 0.98, 95% CI = 0.97-0.99, p = 0.049 were independent late-mortality predictors. Conclusions: BNP measured at hospital admission in patients with NSTEACS is a strong, independent predictor of very long-term all-cause mortality. This study allows raising the hypothesis that BNP should be measured in all patients with NSTEACS at the index event for long-term risk stratification.

    There are limited data on aspirin (ASA) desensitization for patients with coronary artery disease. The aim of the present study was to assess the safety and efficacy of a standard rapid desensitization protocol in patients with ASA sensitivity undergoing coronary angiography. This is a prospective, multicenter, observational study including 7 Italian centers including patients with a history of ASA sensitivity undergoing coronary angiography with intent to undergo percutaneous coronary intervention. A total of 330 patients with history of ASA sensitivity with known/suspected stable coronary artery disease or presenting with an acute coronary syndrome, including ST-segment-elevation myocardial infarction were enrolled. Adverse effects to aspirin included urticaria (n=177, 53.6%), angioedema (n=69, 20.9%), asthma (n=65, 19.7%), and anaphylactic reaction (n=19, 5.8%). Among patients with urticaria/angioedema, 13 patients (3.9%) had a history of idiopathic chronic urticaria. All patients underwent a rapid ASA (5.5 hours) desensitization procedure. The desensitization procedure was performed before cardiac catheterization in all patients, except for those (n=78, 23.6%) presenting with ST-segment-elevation myocardial infarction who underwent the desensitization after primary percutaneous coronary intervention. Percutaneous coronary intervention was performed in 235 patients (71%) of the overall study population. The desensitization procedure was successful in 315 patients (95.4%) and in all patients with a history of anaphylactic reaction. Among the 15 patients (4.6%) who did not successfully respond to the desensitization protocol, adverse reactions were minor and responded to treatment with corticosteroids and antihistamines. Among patients with successful in-hospital ASA desensitization, 253 patients (80.3%) continued ASA for at least 12 months. Discontinuation of ASA in the 62 patients (19.7%) who had responded to the desensitization protocol was because of medical

    Post-cardiac injury syndrome (PCIS) is a syndrome characterized by pericardial and/or pleural effusion, triggered by a cardiac injury, usually a myocardial infarction or cardiac surgery, rarely a minor cardiovascular percutaneous procedure. Nowadays, the post-cardiac injury syndrome, is regaining importance and interest as an emerging cause of pericarditis, especially in developed countries, due to a great and continuous increase in the number and complexity of percutaneous cardiologic procedures. The etiopathogenesis seems mediated by the immunitary system producing immune complexes, which deposit in the pericardium and pleura and trigger an inflammatory response. We present the atypical case of a 76-year-old man presenting with a hydro-pneumothorax, low-grade fever and elevated inflammation markers, after two complex percutaneous coronary interventions, executed 30 and 75 days prior. The clinical features of our case are consistent with the diagnostic criteria of PCIS: prior injury of the pericardium and/or myocardium, fever, leucocytosis, elevated inflammatory markers, remarkable steroid responsiveness and latency period. Only one element does not fit with this diagnosis and does not find any further explanation: the air accompanying the pleural effusion, determining a hydro-pneumothorax and requiring a pleural drainage catheter positioning.

    A 45-year-old previously healthy man with minimal coronary artery disease on imaging presented with an acute MI after sustaining a wasp sting following previous non-eventful exposures throughout his life. This is the first case of Kounis syndrome with optical coherence tomography imaging and proven IgE wasp venom hypersensitivity. The Hymenoptera venom is composed of allergenic proteins and vasoactive amines which are responsible for venom toxicity. This patient also has a history of atopy giving a predisposition for developing IgE-mediated allergic reactions. Hymenoptera stings can be severe in atopic individuals and anaphylaxis may ensue. However, it is a rare cause of myocardial infarction (MI) (Kounis syndrome). Multiple wasp stings in the past may have contributed to sensitisation. Kounis syndrome is a rare clinical manifestation which should remain in the minds of physicians, especially with younger patients with no history of ischaemic heart disease or few risk factors. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    To evaluate the feasibility, diagnostic accuracy, and radiation dose of CT coronary angiography (CTCA) in patients with atrial fibrillation (AF) using 320-detector CT. Thirty-seven patients with persistent AF and suspected coronary artery disease (CAD) were enrolled. All patients underwent both 320-detector CTCA and conventional coronary angiography (CCA). CT image quality and the presence of significant ({>=}50%) stenosis were evaluated by two radiologists blinded to the results of CCA. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated using CCA as the reference standard. Differences in detection of coronary artery stenosis between 320-detector CTCA and CCA were evaluated with McNemar's test. Patient radiation dose was calculated by multiplying dose length product by conversion coefficient of 0.017. In total 474 evaluated coronary segments, 459 (96.8%) segments were diagnostically evaluable. On per-segment analysis, sensitivity, specificity, PPV and NPV were 90.0% (18 of 20), 99.3% (436 of 439), 85.7% (18 of 21) and 99.5% (436 of 438). No significant difference was found between 320-detector CTCA and CCA on the detection of significant stenosis (P = 1.000). Effective doses of 320-detector CTCA was 13.0 {+-} 4.7 mSv. 320-detector CTCA is feasible and accurate in excluding CAD in patients with AF. (orig.)

    Stenting attenuates restenosis, but accelerated coronary artery disease (CAD) adjacent to the stent (peri-stent CAD) remains a concern in metabolic syndrome (MetS). Smooth muscle cell proliferation, a major mechanism of CAD, is mediated partly by myoplasmic Ca2+ dysregulation and store-operated Ca2+ entry (SOCE) via canonical transient receptor potential 1 (TRPC1) channels is proposed to play a key role. Exercise is known to prevent Ca2+ dysregulation in CAD. We tested the hypothesis that MetS increases SOCE and peri-stent CAD and exercise attenuates these events. Groups (n = 9 pigs each) were (i) healthy lean Ossabaw swine fed standard chow, (ii) excess calorie atherogenic diet fed (MetS), and (iii) aerobically exercise trained starting after 50 weeks of development of MetS (XMetS). Bare metal stents were placed after 54 weeks on diets, and CAD and SOCE were assessed 4 weeks later. Coronary cells were dispersed proximal to the stent (peri-stent) and from non-stent segments, and fura-2 fluorescence was used to assess SOCE, which was verified by Ni2+ blockade and insensitivity to nifedipine. XMetS pigs had increased physical work capacity and decreased LDL/HDL (P molecular expression of TRPC1, STIM1, and Orai1 in MetS.

    In the management of non-ST-segment elevation acute coronary syndromes (NSTE-ACS), several studies have shown a reduction in mortality with the use of an invasive strategy in high-risk patients, including diabetic patients. Paradoxically, other studies have shown an under-utilization of this invasive strategy in these patients. The aim of this study is to determine the characteristics of patients managed conservatively and identify determinants of the use of invasive or conservative strategy. Retrospective cohort study conducted in diabetic patients with NSTE-ACS included in the ARIAM-SEMICYUC registry (n=531) in 2010 and 2011. We performed crude and adjusted unconditional logistic regression. We analyzed 531 diabetic patients, 264 (49.7%) of which received invasive strategy. Patients managed conservatively were a subgroup characterized by older age and cardiovascular comorbidity, increased risk of bleeding and the absence of high-risk electrocardiogram (ECG). In diabetic patients with NSTE-ACS, independent predictors associated with conservative strategy were low-risk ECG, initial Killip class>1, high risk of bleeding and pretreatment with clopidogrel. The fear of bleeding complications or advanced coronary lesions could be the cause of the underutilization of an invasive strategy in diabetic patients with NSTE-ACS.

    Circulating endothelial progenitor cells (EPCs) are related to endothelial function and progression of coronary artery disease. There is evidence of decreased numbers of circulating EPCs in patients with a current episode of major depression. We investigated the relationships between the level of circulating EPCs and depression and anxiety in patients with acute coronary syndrome (ACS). Patients with ACS admitted to three Cardiology Intensive Care Units were evaluated by the SCID-I to determine the presence of lifetime and/or current mood and anxiety disorders according to DSM-IV criteria. The EPCs were defined as CD133(+) CD34(+) KDR(+) and evaluated by flow cytometry. All patients underwent standardized cardiological and psychopathological evaluations. Parametric and nonparametric statistical tests were performed where appropriate. Out of 111 ACS patients, 57 were found to have a DSM-IV lifetime or current mood or anxiety disorder at the time of the inclusion in the study. The ACS group with mood or anxiety disorders showed a significant decrease in circulating EPC number compared with ACS patients without affective disorders. In addition, EPC levels correlated negatively with severity of depression and anxiety at index ACS episode. The current study indicates that EPCs circulate in decreased numbers in ACS patients with depression or anxiety and, therefore, contribute to explore new perspectives in the pathophysiology of the association between cardiovascular disorders and affective disorders.

    We tested the hypothesis that lower blood omega-3 (omega-3) fatty acids (FAs) and/or higher trans FAs are associated with the risk of an acute coronary syndrome (ACS). Higher levels of omega-3 FA have been associated with decreased risk of sudden cardiac death. However, their association with ACS risk is unclear. Although higher self-reported intakes of trans FAs have been linked to increased coronary risk, the association between blood levels of trans FA and ACS risk is also unknown. We analyzed the FA composition of whole blood from 94 subjects with ACS and 94 age-, gender-, and race-matched controls. Omega-3 and trans FA associations with ACS were assessed using multivariable models after adjusting for smoking status, alcohol use, diabetes, body mass index, serum lipids, and history of myocardial infarction or revascularization. Subjects' mean age was 47 years, 54% were men, and 80% were Caucasian. Whole blood long-chain omega-3 FA (eicosapentaenoic acid [EPA] plus docosahexaenoic acid [DHA]) content was 29% lower in patients than in controls (1.7 +/- 0.9% vs 2.4 +/- 1.4%, p ACS, but higher blood trans FA content is not. Blood EPA + DHA may serve as a new, modifiable risk factor for ACS.

    We aimed was to assess the association of acute coronary syndrome (ACS) with selected food groups pertinent to non-Mediterranean prototype in Albania, a transitional post-communist country in Southeast Europe. We conducted a case-control study in Tirana in 2003-2006 including 467 non-fatal consecutive ACS patients (370 men aged 59.1±8.7 years, 97 women aged 63.3±7.1 years; 88% response) and a population-based control group (469 men aged 53.1±10.4 years, 268 women aged 54.0±10.9 years; 69% response). A semi-quantitative food frequency questionnaire including 105 food items was administered to all participants based on which the daily calorie intake for selected food groups (meat products, overall oils and fats, sweets, and junk food) was calculated. General linear model was used to assess the association of food groups with ACS. Mean age-adjusted values of meat products, overall oils and fats, sweets and junk food were all considerably higher in cases than controls in both sexes. Cases had significantly higher mean "non-Mediterranean" diet scores (consisting of junk food, sweets, oils and fats except olive oil) than controls (10.3% vs. 5.9% in men and 15.2% vs. 8.3% in women, Pconsumption of processed foods was associated with considerable excess coronary risk which points to serious health implications for the Albanian adult population.

    To assess the impact of on-admission heart rate (HR) in patients presenting with acute coronary syndrome (ACS). Data were collected retrospectively from the second Gulf Registry of Acute Coronary Events. Patients were divided according to their initial HR into: (I: < 60, II: 60-69, III: 70-79, IV: 80-89 and V: ≥ 90 bpm). Patients' characteristics and hospital and one- and 12-month outcomes were analyzed and compared. Among 7939 consecutive ACS patients, groups I to V represented 7%, 13%, 20%, 23.5%, and 37%, respectively. Mean age was higher in groups I and V. Group V were more likely males, diabetic and hypertensive. ST-elevation myocardial infarction was the main presentation in groups I and V. Reperfusion therapies were less likely given to group V. Beta blockers were more frequently prescribed to group III in comparison to groups with higher HR. Groups I and V were associated with worse hospital outcomes. Multivariate analysis showed initial tachycardia as an independent predictor for heart failure (OR 2.2; 95%CI: 1.39-3.32), while bradycardia was independently associated with higher one-month mortality (OR 2.0; 95%CI: 1.04-3.85) CONCLUSION: The majority of ACS patients present with tachycardia. However, low or high HR is a marker of high risk that needs more attention and management.

    The aim of this study was to develop a method for the identification of global weather parameters and patient characteristics associated with a type of heart attack in which there is a sudden partial blockage of a coronary artery. This type of heart attack does not demonstrate an elevation of the ST segment on an electrocardiogram and is defined as a non-ST elevation acute coronary syndrome (NSTE-ACS). Data from the Global Summary of the Day database was linked with the enrollment and baseline data for a phase III international clinical trial in NSTE-ACS in four 48-h time periods covering the week prior to the clinical event that prompted enrollment in the study. Meteorological events were determined by standardizing the weather data from enrollment dates against an empirical distribution from the month prior. These meteorological events were then linked to the patients' geographic region, demographics and comorbidities to identify potential susceptible populations. After standardization, changes in temperature and humidity demonstrated an association with the enrollment event. Additionally there appeared to be an association with gender, region and a history of stroke. This methodology may provide a useful global insight into assessing the biometeorologic component of diseases from international data.

    Coronary heart disease is frequent in the working-age population. Traditional outcomes, such as mortality and hospital readmission, are useful for evaluating prognosis. Fit-for-work is an emerging outcome with clinical as well as socioeconomic significance. We describe the possible benefit of a cardiac rehabilitation (CR) program for return to work (RTW) after acute coronary syndrome (ACS). We evaluated 204 patients with recent ACS. They were divided into 4 groups on the basis of their occupational work load: very light (VL), light (L), moderate (M), and heavy (H). Work-related outcomes were assessed with the Work Performance Scale (WPS) of the Functional Status Questionnaire and as "days missed from work" (DMW) in the previous 4 weeks. The variables considered for outcomes were percent ejection fraction, functional capacity expressed in metabolic equivalents (METs), and participation or non-participation in the CR program (CR+ and CR-). One hundred thirty (66%) patients took part in the CR program. Total WPS scores for CR+ and CR- subgroups were VL group: 18±4 vs. 14±4 (p workplace, in particular among clerical workers.

    Small non-coding microRNAs (miRNAs) are important physiological regulators of post-transcriptional gene expression. miRNAs not only reside in the cytoplasm but are also stably present in several extracellular compartments, including the circulation. For that reason, miRNAs are proposed as diagnostic biomarkers for various diseases. Early diagnosis of acute coronary syndrome (ACS), especially non-ST elevated myocardial infarction and unstable angina pectoris, is essential for optimal treatment outcome, and due to the ongoing need for additional identifiers, miRNAs are of special interest as biomarkers for ACS. This review highlights the nature and cellular release mechanisms of circulating miRNAs and therefore their potential role in the diagnosis of myocardial infarction. We will give an update of clinical studies addressing the role of circulating miRNA expression after myocardial infarction and explore the diagnostic value of this potential biomarker.

    Acute coronary syndrome (ACS) remains a major burden on morbidity and mortality in the United States. Medical professionals and students often use the mnemonic 'MONA' (morphine, oxygen, nitroglycerin and aspirin) to recall treatments for ACS; however, this list of therapies is outdated. We provide a historical perspective on 'MONA,' attempt to uncover its origin in the medical literature, and demonstrate the myriad changes that have occurred over the last 50 years of ACS management. We have developed a novel mnemonic, 'THROMBINS2' (thienopyridines, heparin/enoxaparin, renin-angiotensin system blockers, oxygen, morphine, beta blocker, intervention, nitroglycerin, statin/salicylate) to help bedside clinicians recall all the elements of contemporary ACS management. We demonstrate the mortality benefit for each component of contemporary ACS management, correlating the continued improvement with historical data on mortality after myocardial infarction. We encourage providers to utilize this mnemonic to explore options and guide treatments in ACS patients.

    Current guidelines recommend an early invasive strategy in patients with non-ST segment elevation acute coronary syndromes (NSTEACS). The role of an invasive strategy in frail elderly patients remains controversial. The LONGEVO-SCA registry included unselected NSTEACS patients aged ≥80 years. A geriatric assessment was performed during hospitalization, including frailty. We evaluated the impact of an invasive strategy during the admission on the incidence of cardiac death, reinfarction or new revascularisation at 6-months. From 531 patients included, 145 (27.3%) were frail. Mean age was 84.3 years. Most patients underwent an invasive strategy (407/531, 76.6%). Patients undergoing an invasive strategy were younger and had lower proportion of frailty (23.3% vs 40.3%, pstrategy-frailty was significant (p=0.032) Conclusions: An invasive strategy was independently associated with better outcomes in very elderly patients with NSTEACS. This association was different according to frailty status.

  16. Critical appraisal of ticagrelor in the management of acute coronary syndrome

    Nawarskas JJ

    2011-12-01

    Full Text Available James J Nawarskas, Stanley S SnowdenUniversity of New Mexico College of Pharmacy, Albuquerque, NM, USAAbstract: Ticagrelor is a novel P2Y12 receptor antagonist which, like clopidogrel and prasugrel, functions by blocking adenosine diphosphate-mediated platelet aggregation. However, unlike the aforementioned agents, the binding of ticagrelor to this receptor is reversible. Ticagrelor is also believed to mediate some of its beneficial effects by augmenting the effects of adenosine, which is another unique pharmacologic property of this drug. In terms of antiplatelet effect, ticagrelor is more potent than clopidogrel and produces a faster and stronger inhibition of platelet aggregation. This may also be an advantage of ticagrelor over prasugrel, but this has not been adequately studied. Due to the reversible nature of the binding of ticagrelor to the platelet receptor, ticagrelor has a relatively fast offset of effect, with platelet aggregation approaching pretreatment levels about 3 days after discontinuation of therapy. This has advantages in patients requiring invasive procedures, but also makes medication adherence very important in order to be able to maintain an effective antiplatelet effect. Ticagrelor has been shown to be clinically superior to clopidogrel when given to patients with an acute coronary syndrome, resulting in significantly lower rates of myocardial infarction and vascular death. However, ticagrelor is indicated to be administered with aspirin, and the clinical benefits of ticagrelor may be less when daily dosages of aspirin exceed 100 mg. As expected, bleeding is the most common adverse effect with ticagrelor, although it occurs at rates comparable with those seen for clopidogrel with the exception of noncoronary artery bypass graft-related major bleeding and fatal intracranial bleeds, the latter of which occurs only rarely. Dyspnea is another common adverse effect with ticagrelor, although this is usually not severe and

    Blood glucose is known to be elevated in patients presenting with acute coronary syndromes. However a gap in knowledge exists regarding effective management strategies once admitted to acute care units. It is also unknown what factors (if any) predict elevated glucose values during initial presentation. OBJECTIVES of the study were to characterize blood glucose control in patients admitted to the cardiac care unit (CCU) in Qatar and to determine predictive factors associated with high glucose levels (>10 mmol/l) on admission to the CCU. All data for this study were obtained from the CCU at Heart Hospital in Doha, Qatar. A retrospective chart review was completed for patients admitted to the CCU in Qatar from October 1st, 2012 to March 31st, 2013, of which 283 were included. Baseline characteristics (age, gender, nationality, medical history, smoking status, type of acute coronary syndrome), capillary and lab blood glucose measurements, and use of insulin were extracted. Time spent in glucose ranges of 10 mmol/1 was calculated manually. Univariate and multivariate logistic regression were performed to assess factors associated with high glucose on admission. The primary analysis was completed with capillary data and a sensitivity analysis was completed using laboratory data. Blood glucose values measured on admission and throughout length of stay in the CCU. Capillary blood glucose data showed majority of time was spent in the range of >10 mmol/l (41.95%), followed by 4-8 mmol/l (35.44%), then 8-10 mmol/l (21.45%), and finally 10 mmol/l on admission (p < 0.05) in a univariate analysis but only diabetes remained significant in a multivariate model (OR 23.3; 95% CI, 11.5-47.3). Diabetes predicts high glucose values on hospital admission for patients with ACS and patients are not being adequately controlled throughout CCU stay.

    This study sought to evaluate the incidence of cardiorenal syndrome (CRS) type 1 in a coronary care unit and its association with hospital mortality within 30 days of admission, as well as other epidemiological characteristics. The medical records of all the patients who were hospitalized with the diagnosis of acute heart failure in a 4-year period were reviewed. CRS type 1 was characterized by the presence of acute heart failure and an elevation of serum creatinine ≥0.3mg/dL in comparison to the baseline creatinine calculated by the MDRD75 equation and/or the elevation of ≥50% of the admission serum creatinine within a 48 h period. The incidence of CRS type 1 was 27.87%, 95% CI: 20.13-36.71 (34 of 122). There was a higher frequency of CRS type 1 in those patients who were admitted with the diagnosis of cardiogenic shock (adjusted RR 2.02, 95% CI: 1.20-3.93, p=0.0378) and in those with higher hemoglobin levels (p=0.0412). The CRS type 1 was associated with an increase of 30-day mortality (HR: 4.11, 95% CI: 1.20-14.09, p=0.0244). The incidence of CRS type 1 in the coronary care unit found in our study is similar to those found in foreign studies. The history of stroke and the higher values of hemoglobin were associated with a higher incidence of cardiorenal syndrome type 1. Patients with CRS type 1 had a higher hospital mortality within 30 days of admission. Copyright © 2014 Instituto Nacional de Cardiología Ignacio Chávez. Published by Masson Doyma México S.A.

    To examine the association between abnormal exercise electrocardiographic (E-ECG) test results and mortality (all-cause and that resulting from coronary heart disease [CHD] or cardiovascular disease [CVD]) in a large population of asymptomatic men with metabolic syndrome (MetS). A total of 9191 men (mean age, 46.9 years) met the criteria of having MetS. All completed a maximal E-ECG treadmill test (May 14, 1979, through April 9, 2001) and were without a previous CVD event or diabetes at baseline. Main outcomes were all-cause mortality, mortality due to CHD, and mortality due to CVD. Cox regression analysis was used to quantify the mortality risk according to E-ECG responses. During a follow-up of 14 years, 633 deaths (242 CVD and 150 CHD) were identified. Mortality rates and hazard ratios (HRs) across E-ECG responses were the following: for all-cause mortality: HR, 1.36; 95% confidence interval (CI), 1.09-1.70 for equivocal responses and HR, 1.41; 95% CI, 1.12-1.77 for abnormal responses (P(trend)<.001); for mortality due to CVD: HR, 1.29; 95% CI, 0.88-1.88 for equivocal responses and HR, 2.04; 95% CI, 1.46-2.84 for abnormal responses (P(trend)<.001); and for mortality due to CHD: HR, 1.62; 95% CI, 1.02-2.56 for equivocal responses and HR, 2.45; 95% CI, 1.62-3.69 for abnormal responses (P(trend)<.001). A positive gradient for CHD, CVD, and all-cause mortality rates across E-ECG categories within 3, 4, or 5 MetS components was observed (P<.001 for all). Among men with MetS, an abnormal E-ECG response was associated with higher risk of all-cause, CVD, and CHD mortality. These findings underscore the importance of E-ECG tests to identify men with MetS who are at risk of dying.

Methods: Forty-seven random NSTE-ACS patients and 45 patients with normal coronary arteries (NCA) who underwent coronary angiography were enrolled in the study. GRACE risk score and SYNTAX and Gensini risk scores were used, respectively, for the purpose of clinical risk assessment and angiographic risk scoring. Serum NGAL level was measured via ELISA in peripheral blood samples obtained from the patients at the time of admission. Results: Serum NGAL level was significantly higher in the NSTE-ACS group compared to the control group (112.3±49.6 ng/mL vs. 58.1±24.3 ng/mL, p22) group had statistically significantly higher serum NGAL levels compared to the low SYNTAX (≤22) group (143±29.5 ng/mL vs. 98.7±43.2 ng/mL, p=0.001). Conclusion: NGAL level was positively correlated with lesion complexity and severity of coronary artery disease in patients with NSTE-ACS. Serum NGAL levels on admission are associated with increased burden of atherosclerosis in patients with NSTE-ACS. PMID:25430410

    Although the elderly comprise the majority of acute coronary syndrome (ACS) patients, limited data exist on major adverse cardiovascular events (MACEs) and quality of life (QoL). To study MACEs and QoL prospectively in ACS patients >70years referred for coronary angiography. A prospective observational study that included ACS patients >70years undergoing coronary angiography. The outcomes were MACEs and QoL 3years after inclusion. MACEs were defined as death, recurrent ACS, new-onset of heart failure and repeated revascularization by coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI). A QoL questionnaire was completed by the patients along with a physical examination and a personal interview at the 3-year follow-up. Multivariate analysis was performed to identify the predictors for MACEs. In total, 138 patients (mean age 78.8±3.8years) with ACS were included in the study. Mean follow-up was 1196±296days. In all, 42% of the patients had MACEs and 25% had post-ACS heart failure. The mortality rate was 11%. After adjusting for significant cardiovascular risk factors, the following factors were significantly associated with MACEs: Age, high-sensitive troponin T (hsTNT), use of diuretics and reduced left ventricular ejection fraction (LVEF). Furthermore, the QoL evaluated with SF-36 in survivors from ACS at the end of study was similar to the QoL in an age-matched healthy Swedish population. In this prospective study on elderly ACS patients MACEs still occurred in 42% of the cases (despite low mortality and good QoL), with post-ACS heart failure as the most important event.

    We investigated the utility of noninvasive hemodynamic assessment in the identification of high-risk plaques that caused subsequent acute coronary syndrome (ACS). ACS is a critical event that impacts the prognosis of patients with coronary artery disease. However, the role of hemodynamic factors in the development of ACS is not well-known. Seventy-two patients with clearly documented ACS and available coronary computed tomographic angiography (CTA) acquired between 1 month and 2 years before the development of ACS were included. In 66 culprit and 150 nonculprit lesions as a case-control design, the presence of adverse plaque characteristics (APC) was assessed and hemodynamic parameters (fractional flow reserve derived by coronary computed tomographic angiography [FFR CT ], change in FFR CT across the lesion [△FFR CT ], wall shear stress [WSS], and axial plaque stress) were analyzed using computational fluid dynamics. The best cut-off values for FFR CT , △FFR CT , WSS, and axial plaque stress were used to define the presence of adverse hemodynamic characteristics (AHC). The incremental discriminant and reclassification abilities for ACS prediction were compared among 3 models (model 1: percent diameter stenosis [%DS] and lesion length, model 2: model 1 + APC, and model 3: model 2 + AHC). The culprit lesions showed higher %DS (55.5 ± 15.4% vs. 43.1 ± 15.0%; p stress than nonculprit lesions (all p values statistic [c-index] 0.789 vs. 0.747; p = 0.014) and reclassification abilities (category-free net reclassification index 0.287; p = 0.047; relative integrated discrimination improvement 0.368; p < 0.001) than model 2. Lesions with both APC and AHC showed significantly higher risk of the culprit for subsequent ACS than those with no APC/AHC (hazard ratio: 11.75; 95% confidence interval: 2.85 to 48.51; p = 0.001) and with either APC or AHC (hazard ratio: 3.22; 95% confidence interval: 1.86 to 5.55; p < 0.001). Noninvasive hemodynamic assessment enhanced

    of arterial vasoconstrictor endothelin (ET) and angiotensin (AT) receptors. Our aim was to investigate if the arterial expressions of these receptors are changed in patients with suspected but ruled out acute coronary syndrome (ACS). Small subcutaneous arteries (diameter of 100 microm) were surgically removed...... in the regulation of coronary tone and in the development of atherosclerosis, and may be related to increased cardiovascular risk....

    Aim: The sensitivity and specificity of rest/stress (R/S) myocardial perfusion imaging (MPI) in detecting an acute ischemic coronary syndrome (AICS) was determined in 100 consecutive patients (pts) admitted to the Chest Pain Clinic-Observation Unit (CPC-OU) with chest pain (CP) of suspected cardiac etiology and a negative (neg) or non diagnostic (dx) EKG. There were 57 females and 43 males, 30-83 years of age. 50 studies were performed from 1/15/98 to 4/2/98; 50 from 11/19/99 to 1/10/00. Material and Methods: An AICS was deemed present if a reversible perfusion defect was demonstrated scintigraphically; a ?50% luminal narrow angiographically. No AICS if the pt had a normal R/S MPI, a fixed defect with normal wall motion and thickening, a neg cardiac catheterization, or was free of cardiac symptoms and had no history of a vascular event for 2-3 years post CPC-OU admission. 13 pts with a positive MPI had a cardiac catheterization, none with a neg MPI. SPECT rest MPI's were performed 30-90 minutes (mins) post 10.0 mCi of technetium 99m Sestamibi. SPECT stress MPI's were performed following a 6-8 hour acute myocardial infarction enzyme (CP-MB/Troponin 1) rule out and 30-90 mins post 30.0 mCi of technetium 99m Sestamibi. Results: 29 pts were lost to follow-up. There were 12 true positive, 5 false positive, 54 true negative and 0 false negative studies. The sensitivity, specificity, positive and negative predictive value of a R/S MPI in detecting an AICS is 100%, 91%, 70% and 100%, respectively. An AICS was detected in 12% of pts admitted to the CPC-OU; a finding that correlates with its reported incidence of 2-12%. 6 were managed medically, 3 required emergent bypass surgery, 3 were stented. Conclusion: R/S MPI should be included in the CPC-OU dx work-up of pts with CP of suspected cardiac etiology to prevent missed AICS diagnoses. Patient care will be optimized and health care and medical malpractice awards for failure to diagnosis an acute myocardial infarction
